  Synthesis and photochemical behavior of donor–acceptor systems obtained from chloro-1,4-naphthoquinone attached to trans-aminostilbenes

  摘要：

  2-Chloro-1,4-naphthoquinone was covalently attached to six differently substituted and positional isomers of transaminostilbene, forming a novel donor-acceptor system (QST), in which a good fluorophore is bonded via an NH group to an active redox quencher. The new systems were characterized by FT-IR, H-1 NMR, HR-MS, UV-Vis and fluorescence spectroscopy. The redox state of the system QST/QH(2)ST controls its photochemical properties. While the QST's behave as an 'auto-quenching system' and are nonfluorescent, the reduced hydroquinonic system (QH(2)ST) affects appreciably the emission properties of the molecule.

  A liquid crystal alignment agent, a liquid crystal alignment film, and a liquid crystal display device are provided. The liquid crystal alignment agent includes a polymer composition (A-1) and a solvent (B). The polymer composition (A-1) is obtained by reacting a tetracarboxylic acid dianhydride compound (a) with a diamine compound (b). The diamine compound (b) includes at least one type of diamine (b-1) represented by formula (I) and at least one type of diamine (b-2) having the structure represented by formula (II). The liquid crystal alignment agent can be made into a liquid crystal display device having good uniformity of pretilt angle after ultraviolet irradiation.
