Description

【0001】
【発明の属する技術分野】
本発明は、液晶材料や電子材料として有用な新規なトリフェニレン誘導体に関する。
【0002】
【従来の技術】
液体でありながら分子配列に秩序性を有するという特異な性質を示す液晶は、その特異性故の有用な用途が示されている。その典型例は液晶表示素子(LCD)であり、今や産業上重要な地位を占めるに至っている。このLCDに用いられている、TNあるいはSTN液晶は分子の形状により分類すれば棒状液晶に属するが、近年、これらとは分子の形状の異なる円盤状をした、ディスコティック液晶にも衆目が注がれるようになっている。例えば、D.Adam他、著、Nature誌、371巻、141−143ページ(1994年刊)に記載された、電荷輸送材料としての高速性であり、また、特開平7−146409号公報等に記載された、特異な光学異方性を利用した光学補償板である。
【0003】
さらに、トリフェニルアミン誘導体およびフェニルカルバゾール誘導体は、電子写真や電界発光素子に有用な素材として用いられ得ることが知られている。加えて、特願平8−233467号明細書に記載されているように、近年携帯電子機器の電源として重要になっている、リチウムイオン二次電池の性能向上に有用な役割を担い得ることが知られている。単分子の状態での分子の示す性質や機能が、集合した分子の状態においては変化し得るることはよく知られており、超分子なる言葉で語られることもある。古くから知られた典型例は、色素の会合による吸収スペクトルの変化であり、単分子状態での吸収波長より長波長側にシャープなスペクトルを示すJ−会合体は、銀塩写真の分光増感色素としてその特徴を有するが故に用いられている。
【0004】
従って、トリフェニルアミン誘導体およびフェニルカルバゾール誘導体においても、同様に集合状態による有用な性質や機能の発現が期待される。かかる観点から、トリフェニレン誘導体における同一分子種を複数個置換可能な構造および液晶性の発現は、極めて興味深いものである。
【0005】
これらの状況を背景として、ディスコティック液晶性を示し得る新たな化合物の発見とともに、トリフェニルアミン誘導体およびフェニルカルバゾール誘導体を置換基として有するトリフェニレン誘導体などの円盤状化合物の出現が期待されている。しかし、ディスコティック液晶においてはその発見が1977年であること、また、関心が高まったのが極めて近年であることから、その要望に対しては必ずしも十分には答えられてはいない。
【0006】
【発明が解決しようとする課題】

BACKGROUND OF THE INVENTION
The present invention relates to a novel triphenylene derivative useful as a liquid crystal material or an electronic material.
[0002]
[Prior art]
A liquid crystal exhibiting a unique property of having an ordering in the molecular arrangement while being a liquid has shown a useful application due to its specificity. A typical example is a liquid crystal display (LCD), which has now occupied an important industrial position. The TN or STN liquid crystal used in this LCD belongs to a rod-like liquid crystal if classified according to the shape of the molecule, but in recent years, attention has been paid to the discotic liquid crystal having a disc shape with a different molecular shape. It is supposed to be. For example, D.D. Adam et al., Book, Nature, 371, pages 141-143 (1994), is a high-speed property as a charge transport material, and also described in JP-A-7-146409, etc. It is an optical compensator using an optical anisotropy.
[0003]
Furthermore, it is known that triphenylamine derivatives and phenylcarbazole derivatives can be used as materials useful for electrophotography and electroluminescence devices. In addition, as described in the specification of Japanese Patent Application No. 8-233467, it can play a useful role in improving the performance of lithium ion secondary batteries, which have recently become important as power sources for portable electronic devices. Are known. It is well known that the properties and functions of molecules in the state of a single molecule can change in the state of an assembled molecule, sometimes referred to as the term supramolecule. A typical example that has been known for a long time is a change in absorption spectrum due to association of dyes. A J-aggregate showing a sharp spectrum on the longer wavelength side than the absorption wavelength in a monomolecular state is a spectral sensitization of silver salt photographs. It is used because of its characteristics as a pigment.
[0004]
Therefore, the triphenylamine derivative and the phenylcarbazole derivative are also expected to exhibit useful properties and functions depending on the aggregation state. From such a viewpoint, the structure capable of substituting a plurality of the same molecular species in the triphenylene derivative and the development of liquid crystallinity are extremely interesting.
[0005]
Against this background, the discovery of new compounds capable of exhibiting discotic liquid crystallinity and the appearance of discotic compounds such as triphenylene derivatives having triphenylamine derivatives and phenylcarbazole derivatives as substituents are expected. However, since the discovery of the discotic liquid crystal is 1977 and the interest has increased in recent years, the demand has not been fully answered.

An object of the present invention is to provide a discotic compound having a triphenylamine derivative and a phenylcarbazole derivative as a substituent.

1.07 g (0.5 mmol) 2,3,6,7,10,11-hexakis- [6- (4-iodophenyloxy) hexyloxy] triphenylene, 2.51 g (15 mmol) carbazole, 3.43 g 50 ml of o-dichlorobenzene was added to (18 mmol) of cuprous iodide and 4.14 g (30 mmol) of potassium carbonate (anhydrous) and stirred at reflux for 24 hours. The reaction mixture was allowed to cool to room temperature, filtered, the filtrate was concentrated under reduced pressure, and purified by silica gel column chromatography (eluent: dichloromethane / hexane = 8/2) to obtain the desired product. Yield 1.10 g (92.8% yield)
