Abstract:
A chromene compound represented by the formula (1), wherein,R1 is an alkyl group, an alkoxy group, an aralkoxy group, an amino group, a substituted amino group, a cyano group, a substituted or unsubstituted aryl group, a halogen atom, an aralkyl group, a monovalent substituted or unsubstituted heterocyclic group having a nitrogen atom as a hetero atom and bonded to the indene ring through the nitrogen atom, or a monovalent condensed heterocyclic group in which said heterocyclic group is condensed with an aromatic hydrocarbon ring or an aromatic heterocyclic ring, and p is an integer of from 0 to 3; a divalent group represented by the following formula (2), â€ƒis an aromatic hydrocarbon group or an unsaturated heterocyclic ring; R2 is an alkyl group, an alkoxy group, an aralkoxy group, an amino group, a substituted amino group, a cyano group, a substituted or unsubstituted aryl group, a halogen atom, an aralkyl group, a monovalent substituted or unsubstituted heterocyclic group having a nitrogen atom as a hetero atom and is bonded to the ring of the group represented by the above formula (2) through the nitrogen atom, or a monovalent condensed heterocyclic group in which said heterocyclic group is condensed with an aromatic hydrocarbon ring or an aromatic heterocyclic ring, and q is an integer of from 0 to 3; R3 and R4, independently from each other, represent a group of formula (3), formula (4), substituted or unsubstituted aryl group, or substituted or unsubstituted heteroaryl group; â€ƒwherein R5 is a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group, R6 is a hydrogen atom, an alkyl group or a halogen atom, and n is an integer of from 1 to 3; â€ƒwherein R7 is a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group, and m is an integer of from 1 to 3; or R3 and R4 are groups which together form an aliphatic hydrocarbon ring or an aromatic hydrocarbon ring; and X is represented by one of the following formula, â€ƒwherein Z is an oxygen atom or a sulfur atom, R8 is an alkylene group with 1 to 6 carbon atoms, and a, b, c and d are, independently of each other, integers of from 1 to 4.
