Magnesium Tetraethynylporphyrins Linked with Diketopyrrolopyrroles for Small Molecule Organic Solar Cells

摘要

Porphyrin-based small-molecule electron donors have recently emerged as a new option for use in bulk heterojunction organic solar cells. Our group has applied the meso-ethynyl-linkages concept to realize maximum conjugation of porphyrins for efficient light absorption and high carrier mobility. Herein, we report to synthesize Mgtetraethynylporphyrin (TEP) having two Diketopyrrolopyrrole (DPP) units.
