The present invention relates to novel charge transfer materials which have both the advantageous properties of amorphous materials such as structural flexibility and uniformity over large areas, and those of crystalline materials such as molecular orientation and which are excellent in charge transferability, thin-film formability, and durability of various types. The liquid crystalline charge transfer materials have the following structure (A) containing a fluorescent skeletal structure Y, and the core Z of a liquid crystal:
in which R1, which may directly be combined with Z without interposing X1, represents a saturated or unsaturated, and linear, branched or cyclic hydrocarbon group having 1 to 22 carbon atoms; and X1 and X2 represent oxygen atom, sulfur atom, or -CO-, -OCO-, -COO-, -N=CH-, -CONH-, -NH-, -NHCO- or -CH2- group; or
in which R1 and R2, which may directly be combined with Y without interposing X1 and X2, each represent a saturated or unsaturated, and linear, branched or cyclic hydrocarbon group having 1 to 22 carbon atoms; and X1 and X2 represent oxygen atom, sulfur atom, or -CO-, -OCO-, -COO-, -N=CH-, -CONH-, -NH-, -NHCO- or - CH2- group.
本发明涉及新型电荷转移材料,它既具有非晶体材料的结构柔性和大面积均匀性等优越性能,又具有晶体材料的分子取向等性能,而且在电荷转移性、薄膜成型性和各种耐久性方面都非常出色。液晶电荷转移材料具有如下结构 (A) 含有荧光骨架结构 Y 和液晶核心 Z:
其中 R1(可直接与 Z 结合而无需插入 X1)代表具有 1 至 22 个碳原子的饱和或不饱和、直链、支链或环状烃基;X1 和 X2 代表氧原子、硫原子或-CO-、-OCO-、-COO-、-N=CH-、-CONH-、-NH-、-NHCO- 或-CH2-基团;或
其中 R1 和 R2(可直接与 Y 结合而无需插入 X1 和 X2)各自代表具有 1 至 22 个碳原子的饱和或不饱和、直链、支链或环状烃基;X1 和 X2 代表氧原子、硫原子或-CO-、-OCO-、-COO-、-N=CH-、-CONH-、-NH-、-NHCO- 或-CH2-基团。
