Abstract:
A series of metal(II)‐substituted 5,10,15,20‐tetrakis[4‐(diphenylamino)phenyl]porphyrins ( P ) were designed and synthesized. Incorporation of the flexible and strong electron‐donating triphenylamine substituent endowed the porphyrins with enhanced solubility and intermolecular interactions. The distinct properties arising from different central metal ions were investigated by studying the absorption spectra, electrochemistry behavior, charge transport properties, thermal stability, and morphology characterization of the porphyrins. The Pd II 5,10,15,20‐tetra(4‐diphenylaminophenyl)porphyrins ( P Pd ) were found to have more matching energy levels with methyl [6,6]‐phenyl‐C‐61‐butyrate (PC 61 BM), higher hole mobility and longer triplet exciton lifetime. Bulk heterojunction solar cells based on porphyrins and PC 61 BM have been fabricated, with P Pd ‐based solar cells exhibiting greatly enhanced photovoltaic performance originating from a combination of elements. These results will help guide the future molecular design of porphyrins for application in organic small molecule bulk heterojunction solar cells.
