<p>PROBLEM TO BE SOLVED: To provide a new triindole derivative enabling to form into a thin film, which has conventionally been difficult, and remarkably useful as a donor material. SOLUTION: This triindole derivative features being represented by general formula (1), wherein R1 is a 2-24C linear or branched alkyl group or general formula (4), wherein R1 is a 2-24C linear or branched alkyl group; and R3 is -CN or at least one of groups represented by structural formulas (a) and (b).</p> |
