NOVEL CHROMENE DYE AND A PREPARING METHOD OF THE SAME

摘要

PURPOSE: A chromene-based dye is provided to have excellent photoreactivity, thereby being used as a dye for a dye-sensitized solar cell. CONSTITUTION: A chromene-based dye is represented by chemical formula 1. In chemical formula 1, each of D1, D2, D3, and D4 is an electron donor; R1 is one selected from hydrogen, oxygen, a substituted or unsubstituted C1-C30 alkyl group, a substituted or unsubstituted C1-30 alkoxy group, a substituted or unsubstituted C6-C30 aryl group, a substituted or unsubstituted C2-C30 heteroaryl group; and R2 is an electron acceptor. A dye for a dye-sensitized solar cell comprises the chromene-based dye.
