<p><P>PROBLEM TO BE SOLVED: To provide a composition having a long light absorption end wavelength. <P>SOLUTION: The composition includes a first compound having a structural unit represented by formula (1) and a second compound comprising only a structural unit different from the structural unit represented by formula (1). In formula (1), Q<SP>1</SP>and Q<SP>2</SP>each independently represent -S-, -O-, -Se-, or -N(R<SP>3</SP>)-; and R<SP>1</SP>, R<SP>2</SP>, and R<SP>3</SP>each independently represent a hydrogen atom, a halogen atom, an alkyl group, an alkyloxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, an arylalkyl group, an arylalkyloxy group, an arylalkylthio group, an acyl group, an acyloxy group, an amide group, an acid imide group, an amino group, a substituted amino group, a substituted silyl group, a substituted silyloxy group, a substituted silylthio group, a substituted silylamino group, a monovalent heterocyclic group, a heterocyclicoxy group, a heterocyclicthio group, an arylalkenyl group, an arylalkynyl group, a carboxyl group, or a cyano group. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
