Title:
CARBAZOLE RING-CONTAINING MONOMER, CARBAZOLE RING-CONTAINING POLYMER AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JP3200467
Kind Code:
B2
Abstract:
PURPOSE: To obtain the carbazole ring-contg. polymer having excellent solubility in general-purpose solvents and workability by polymerizing the specific carbazole ring-contg. monomer.
CONSTITUTION: The carbazole ring-contg. monomer expressed by formula I (where R1, R2 denote a substituent, such as hydrogen atom, lower alkyl group; R3 denotes a hydrogen atom, lower alkyl group, lower alkoxy group, halogen atom, hydroxyl group, cyano group, nitro group; X denotes 2 to 15 alkylene group), by which the carbazole ring-contg. polymer expressed by formula II (where m is 2000 to 1000000) is obtd. This polymer exhibits the excellent solubility in not only the general-purpose low boiling solvents, such as chloroform, tetrahydrofuran, benzene and toluene, but also high boiling org. solvents, such as chlorobenzene and dimethyl formamide. Since the liquid crystalline structure is incorporated into the polymer, the polymer has excellent orientability and has excellent photosensitiveness and photoelectric conversion characteristics.
