Description
光学異方性薄膜は従来技術において周知である。ポリビニルアルコール(PVA)膜は一軸延伸及び有機染料又はヨウ素での着色により光学異方性を獲得する。しかしながら、PVAベースの薄膜は熱的安定性が低いといった特徴であり、それにより幾らかの実用的な用途がかなり制限を受けることになる。PVAベースの膜は、例えば、非特許文献1に記載されている。
有機染料分子に類似した分子構造を備えてはいるが、可視スペクトル領域にて吸収しない有機共役化合物は、液晶ディスプレイの位相差板及び補償板を製造するために使用され得る。
本明細書において使用されているように、「多環式有機化合物」なる用語は、以下の式(I)に示されるように結合された少なくとも二つのフェニル環であって、置換された、又は置換されていないフェニル環、の連続体を参照し、同連続体は選択的に、更なる共有結合により二つの隣接するフェニル環が結合している少なくとも一つの二価の基を含み、かつ同連続体は選択的に二つの隣接するフェニル環の間に少なくとも一つの複素環基を含む。
「薄膜」なる用語は、約1000ミクロン未満の厚みを有する膜を定義する。
本発明の一実施形態において、有機化合物は更に二つの隣接するフェニル環の間に配置される少なくとも一つの複素環基を含む。本発明の別の実施形態において、有機化合物は更に、二つの隣接するフェニル環の間に配置される少なくとも二つの同一の、若しくは異なる複素環基を含む。
異方性光学膜の一実施形態において、酸性基A及びBは、スルホン基、カルボキシル基及びホスホン酸基からなる群より独立して選択される。異方性光学膜の別の実施形態において、有機化合物はすでに記載された構造式(II)を有する。異方性光学膜の更に別の実施形態において、有機化合物は、すでに記載された二価の基X1、X2及びX3を含む構造式(III)を有する。異方性光学膜の別の実施形態において、開示された有機化合物は二価のXi基を含む式(III)に類似する構造式を有し、ここで、iは1乃至(n−1)の任意の値であり、Xi基のすべてが、フェニル環の鎖を形成する結合に関して任意の一方の側にある。
本発明の一実施形態において、異方性光学膜は式(I)の化合物を含み、同化合物において、少なくとも一つの複素環基が二つの隣接するフェニル環の間に配置されている。異方性光学膜の別の実施形態において、有機化合物は更に、二つの隣接するフェニル環の間に配置される同一の、又は異なる複素環基を少なくとも二つ含む。異方性光学膜の好ましい実施形態において、同複素環基はベンゾジオキサゾール、ベンゾジイミダゾール、ピリジン、ピラジン、ピリミジン及び1,3,4−オキサジアゾールから選択される。
第三の態様において、本発明は基質に異方性光学膜を形成する方法を提供し、同方法は以下の工程を含む。
(3)固体層を形成するために乾燥する工程。
開示された発明の一実施形態において、同方法は更に、液体層を適用する工程と同時に、若しくは同適用工程の後であって乾燥工程より前に、外的な整合作用を溶液の液体層に付与する工程を更に含む。外的な整合作用は、溶液を、Mayerロッド(ワイヤで巻回された円筒状のロッド)、スロット−ダイ又は当該技術分野において周知のその他任意の技術からなる群より選択される任意の工具によって表面に薄く塗布される場合に適用される剪断力のような機械的な応力にて生成され得る。機械的な応力の他に、当業者は、必要とされるモードにおいて基質上に膜の配向を可能にする、電気的応力、電子−磁気的応力、重力又は任意のその他の応力の適用を使用できる。
本発明の一実施形態において、開示された方法は更に、有機化合物の二つの隣接するフェニル環の間に配置される少なくとも一つの複素環基を含む。本発明の方法の別の実施形態において、有機化合物は更に、二つの隣接するフェニル環の間に配置される同一の、又は異なる少なくとも二つの複素環基を含む。好ましい一実施形態において、同複素環基はベンゾジオキサゾール、ベンゾジイミダゾール、ピリジン、ピラジン、ピリミジン及び1,3,4−オキサジアゾールから選択される。
本発明の別の実施形態において、基質はその表面を親水性とするために予め処理される。
その他の実施形態において、乾燥工程は昇温下で実施される。好ましい実施形態において、温度はおおよそ20乃至60℃の範囲である。
4,4’−(5,5−ジオキシドジベンゾ[b,d]チエン−3,7−ジイル)ジベンゼンスルホン酸(1g)を実施例1に記載した方法にて取得し、3.8mlの蒸留水及び1.1mlの10%含水ナトリウム溶液と混合し、リオトロピック液晶溶液が形成されるまで(約1時間)、室温(23℃)にて撹拌した。
