THIOPHENE COMPOUND HAVING PHOSPHORIC ESTER AND PROCESS FOR PRODUCING THE SAME

摘要

A thiophene compound having a phosphate group, for example, one represented by the formula [1]. The compound has high resistance to heat and oxidation and can be improved in solubility or dispersibility in various solvents. (see formula 1) (In the formula, R1 and R2 each independently represents, e.g., hydrogen, halogeno, cyano, or phenyl optionally substituted by W; and R3 to R6 each independently represents -OR7, SR8, or -NR9 2, provided that R7 to R9 each independently represents hydrogen, C1-10 alkyl, or phenyl optionally substituted by W and W represents halogeno, cyano, nitro, hydroxyl, mercapto, amino, formyl, carboxy, C1-10, alkyl, etc.)
