Title:
SUBSTITUENT-DISSOCIABLE DIKETOPYRROLOPYRROLE DERIVATIVE AND ORGANIC SEMICONDUCTOR MATERIAL OBTAINED THEREFROM
Document Type and Number:
Japanese Patent JP2015030725
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a diketopyrrolopyrrole derivative that has sufficient solubility before heating and generates a hydroxyl group by heating, which can extremely decrease solubility with various solvents, and that shows no shift to a shorter wavelength region in absorption characteristics thereof when a substituent is dissociated.SOLUTION: A substituent-dissociable diketopyrrolopyrrole derivative expressed by general formula (I) below is provided. In general formula (I), R represents a substituted or unsubstituted alkyl group; X represents a substituted or unsubstituted alkyl group; Ar represents a substituted or unsubstituted aromatic group or a substituted or unsubstituted heteroaromatic group; and n represents an integer of 1 to 4.
