Title:
ANTHRACENYL ORGANIC DYE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/167315
Kind Code:
A1
Abstract:
Provided are an anthracenyl organic dye and a preparation method therefor. The organic dye has the structure shown in formula (I) or formula (II), wherein Ra, Rb and R2-1 – R2-4 are defined in the present document. The organic dye is prepared by modifying Ra and Rb on an anthracenyl group, or by modifying Ra and Rb on anthracenyl groups connected by an aryl group or a heteroaryl group. When applied to a dye-sensitised solar cell, the organic dye significantly increases the photoelectric conversion efficiency of the cell. The preparation method for the organic dye is simple, the raw materials are widely available, costs are low, and industrial production may be implemented.
