Description
本発明は、光機能性物質として有用な新規の化合物に関する。 The present invention relates to a novel compound useful as a photofunctional substance.
自然界の植物や光合成細菌は太陽光子を捕集し、そのエネルギーを化学エネルギー変換や物質生産に効率よく利用されている。最近、自然界の光捕集アンテナ系を有機色素分子で模倣・構築し、太陽光をエネルギー源とする人工光合成の実現が注目されている。とくに、太陽光全体のエネルギーの約7割を占める可視光の有効利用は持続可能なエネルギー源の開拓と関連して、近年基礎・応用の両面から関心が集まりつつである。 Natural plants and photosynthetic bacteria collect solar photons and use them efficiently for chemical energy conversion and substance production. Recently, the realization of artificial photosynthesis using sunlight as an energy source by imitating and constructing a natural light collecting antenna system with organic dye molecules has been attracting attention. In particular, the effective use of visible light, which accounts for about 70% of the total energy of sunlight, has recently attracted interest from both basic and applied aspects in connection with the development of sustainable energy sources.
光機能性分子を設計し光機能性材料を創製するには、通常では密度の極めて低い太陽光子を効率よく捕捉するために、できるだけ数多くの色素ユニットを分子内に集積化して大きな光吸収断面積を有するようにしなければならない。一方、代表的な有機色素分子であるポルフィリンはπ−共役電子系をもつ大環状有機化合物であり、可視光領域において極大吸収を持つため、太陽光をエネルギー源とする機能性材料の開発に非常に都合の良いモチーフである。さらに、ポルフィリンとその誘導体は光捕集だけでなく、光エネルギー移動や光誘起電子移動、触媒作用等多彩な機能を示す。 In order to design optical functional molecules and create optical functional materials, it is usually necessary to integrate as many dye units as possible in the molecule in order to efficiently capture very low density photons. Have to have. On the other hand, porphyrin, a typical organic dye molecule, is a macrocyclic organic compound with a π-conjugated electron system and has maximum absorption in the visible light region, so it is extremely useful for the development of functional materials that use sunlight as an energy source. This is a convenient motif. Furthermore, porphyrin and its derivatives show various functions such as light energy transfer, photoinduced electron transfer, and catalytic action as well as light collection.
これまでに、ポルフィリン単一分子とその機能の検討が主になされてきたが、ポルフィリン同士間の相互作用や2分子反応による活性体の失活のため、ポルフィリンの特性を十分に発揮する光機能性材料を得ることができなかった。最近、ポルフィリンを高分子鎖に導入することが試みされている。ポリマー主鎖または側鎖にポルフィリンを導入してポルフィリンの集積化を試みるものである〔Eberspacher, T. A., Collman, J/P.; Chidsey, C.E.D.; Donohue, D.L;
Van Ryswyk, H.; Langmuir, 2003: 19(9);
3814-3821(非特許文献1)、Zhang, Z.; Hou, S.; Zhu, Z.; Liu, Z.; Langmuir: 2000:
16(2); 537-540(非特許文献2)〕。しかし、通常の高分子ではポリマー鎖が絡み合いやすく、色素分子を整列することや空間配置を制御することが困難である。また、ポルフィリンをモノマーユニットそのものとして使用した場合、でき上がったポリマー鎖は硬直な構造のゆえに、分子間の相互作用が格段に強くなり、その溶解性が乏しいばかりか、ポリマー鎖の成長さえ難しくなり、一分子あたりの色素分子の数が非常に限られてしまう欠点が残されている。したがって、ポリマーを利用するこれらの手法も、光捕集や光導電性などにおいて優れた光機能性材料を得るのに充分なものではない。

16 (2); 537-540 (Non-Patent Document 2)]. However, in ordinary polymers, polymer chains are easily entangled, and it is difficult to align the dye molecules and control the spatial arrangement. In addition, when porphyrin is used as the monomer unit itself, the resulting polymer chain has a rigid structure, so the interaction between molecules becomes much stronger, its solubility is poor, and even the growth of the polymer chain is difficult, The drawback remains that the number of dye molecules per molecule is very limited. Therefore, these techniques using a polymer are not sufficient for obtaining an optical functional material excellent in light collection and photoconductivity.

FIG. 1 outlines a general reaction scheme for synthesizing the dendrimer compounds of the present invention, and FIGS. 2 and 3 show examples of the dendrimer compounds according to the present invention described in the following examples. Shows the synthesis scheme in more detail.
図1に示すように、本発明のマルチポルフィリンデンドリマー化合物は、一般に、ポルフィリン誘導体からデンドロンの世代を増やす反応(1)(例えば、エステル化反応、アミド化反応、エーテル反応)、およびその後の脱保護反応(2)を繰り返すことにより、ポルフィリン環を含む構造ユニットを合成した後、該構造ユニットをコアユニットであるヘキサ(4−置換フェニル)ベンゼンとのカップリング反応(例えば、エステル反応、アミド反応、エーテル反応)に供することにより合成することができる。なお、図1中、Aはカルボン酸、ベンジルブロマイド、エチニールなどの反応基を表わし、Bはエステル、ベンジルアルコール、三重結合などの保護した官能基を表わし、Cは水酸基、ハロゲンなどの反応基を表わす。また、図1では、図を複雑にしないために、式1の一連の化合物の合成法について示していないが、世代を増やす反応(1)においてポルフィリン誘導体を下記の化合物と反応させた後、式2または式3の化合物の場合と以下同様の反応工程を経て式1の化合物を合成することができる。
As shown in FIG. 1, the multiporphyrin dendrimer compound of the present invention generally has a reaction (1) for increasing the generation of dendron from a porphyrin derivative (for example, esterification reaction, amidation reaction, ether reaction) and subsequent deprotection. After synthesizing a structural unit containing a porphyrin ring by repeating the reaction (2), the structural unit is coupled with hexa (4-substituted phenyl) benzene as a core unit (for example, ester reaction, amide reaction, It can synthesize | combine by using for ether reaction.

In addition, in FIG. 1, in order not to complicate the figure, a method for synthesizing a series of compounds of Formula 1 is not shown, but after reacting a porphyrin derivative with the following compound in the reaction (1) for increasing the generation, The compound of
本発明のマルチポルフィリンデンドリマー化合物は、可視の吸収能に優れ、例えば414nmにおけるモル吸光係数は106〜107M−1cm−1の大きさに達し、しかもその吸光係数はポルフィリンユニットの数に増大して比例する。これは本発明の化合物は、多数のポルフィリンが車輪状を成して配列されている特異な構造を有しているためと推測される。すなわち、本発明のマルチポルフィリンデンドリマー化合物では、すべてのポルフィリンユニットがデンドリマー構造の外表面において言わば同じ化学・物理環境に配列されているので、従来の直鎖状ポルフィリンポリマーとは著しく異なり、分子間の会合を抑制してポルフィリン本来の性質を発揮させながら巨大な光吸収面積を呈するとともに、そのポルフィリンユニットの数によりその大きさを容易に制御することができるためと理解される。 The multiporphyrin dendrimer compound of the present invention is excellent in visible absorption capacity, for example, the molar extinction coefficient at 414 nm reaches a magnitude of 10 6 to 10 7 M −1 cm −1 , and the extinction coefficient is equal to the number of porphyrin units. Increased and proportional. This is presumably because the compound of the present invention has a unique structure in which a large number of porphyrins are arranged in a wheel shape. That is, in the multiporphyrin dendrimer compound of the present invention, all porphyrin units are arranged in the same chemical / physical environment on the outer surface of the dendrimer structure, which is significantly different from conventional linear porphyrin polymers. It is understood that while suppressing the association and exhibiting the intrinsic properties of porphyrin, it exhibits a huge light absorption area and its size can be easily controlled by the number of porphyrin units.
かくして、本発明は、車輪状マルチポルフィリンデンドリマーの構築を通じてポルフィリンの空間配置を制御することにより、巨大な可視光吸収断面積、優れた光捕集能、良好な溶解性など新しいタイプの光機能性材料の創製の手法を確立したものである。以下に、本発明の特徴をさらに具体的に示すため、実施例を示すが、本発明はこれらの実施例に限定されるものではない。 Thus, the present invention controls the spatial arrangement of porphyrins through the construction of a wheel-shaped multiporphyrin dendrimer, thereby creating a new type of optical functionality such as a huge visible light absorption cross section, excellent light collection ability, and good solubility. This is a method for creating materials. Examples are given below to illustrate the features of the present invention more specifically, but the present invention is not limited to these examples.

マルチポルフィリンデンドリマー化合物の物性評価
実施例1で合成した車輪状マルチポルフィリンデンドリマー化合物はいずれも通常の有機溶媒(例えば、クロロホルム、塩化メチレン、THFなど)に優れた溶解性を示した。また、外表面にポリベンジルエーテルデンドロンを持つため,成膜性にも優れていた。
次に、紫外・可視吸収スペクトルや蛍光発光スペクトルの測定から、これらのマルチポルフィリンデンドリマーはポルフィリンユニットの数が増大しても、吸収バンドの位置(図9)や蛍光バンドの位置(表1)がほとんど変わらないことが分かった。一方、これらの化合物はモル吸光係数がポルフィリンユニットの数に比例して増大し、可視光領域において巨大な光吸収断面積を有することが明らかである(表1)。すなわち、本発明の車輪状マルチポルフィリンデンドリマー化合物は、多数のポルフィリンユニットを有するが、基底状態や光励起一重項状態において会合による分子間の相互作用がほとんど見られない。
Evaluation of Physical Properties of Multiporphyrin Dendrimer Compound All the wheel-shaped multiporphyrin dendrimer compounds synthesized in Example 1 showed excellent solubility in ordinary organic solvents (for example, chloroform, methylene chloride, THF, etc.). In addition, because it has polybenzyl ether dendron on the outer surface, it has excellent film forming properties.
Next, from the measurement of ultraviolet / visible absorption spectrum and fluorescence emission spectrum, these multiporphyrin dendrimers have an absorption band position (FIG. 9) and a fluorescence band position (Table 1) even if the number of porphyrin units increases. I found it almost unchanged. On the other hand, it is clear that these compounds have a molar extinction coefficient that increases in proportion to the number of porphyrin units and have a huge light absorption cross section in the visible light region (Table 1). That is, the wheel-shaped multiporphyrin dendrimer compound of the present invention has a large number of porphyrin units, but there is almost no interaction between molecules in the ground state or photoexcited singlet state.
本発明に従う車輪状マルチポルフィリンデンドリマー化合物ではすべてのポルフィリンユニットがデンドリマー構造の外表面に位置し、個々のポルフィリンにおいて外部からのアクセスが高い自由度を有しており、光誘起エネルギー移動や光誘起電子移動、触媒反応などにおいて非常に有利な構造となっている。
かくして、本発明のマルチポルフィリンデンドリマー化合物は、センサ、オプトーキラルシグナリング剤、光触媒、金属ポルフィリン触媒、重合開始剤、光捕集剤、分子導線、金属ナノ微粒子鋳型、無機有機複合材料の鋳型、オプトナノデバイス、太陽電池材料等への各種の用途が期待される。
In the wheel-shaped multiporphyrin dendrimer compound according to the present invention, all porphyrin units are located on the outer surface of the dendrimer structure, and each porphyrin has a high degree of freedom of external access, so that photoinduced energy transfer and photoinduced electron It has a very advantageous structure in transfer and catalytic reaction.
Thus, the multiporphyrin dendrimer compound of the present invention comprises a sensor, an optochiral signaling agent, a photocatalyst, a metal porphyrin catalyst, a polymerization initiator, a light collector, a molecular wire, a metal nanoparticle template, an inorganic organic composite template, an opt Various applications to nanodevices, solar cell materials, etc. are expected.
