PORPHYRIN AND CONDUCTIVE POLYMER COMPOSITIONS FOR USE IN SOLID-STATE ELECTRONIC DEVICES

摘要

Compositions comprising porphyrinic macrocycles and conjugated polymers such as polythiophene for use in organic electronic devices including solar cells are presented. Covalent linkage of a porphyrinic macrocycle to a polymer allows tuning of electronic and spectroscopic properties of conjugated polymers and can improve the heat stability of the system relative to a blended comparison. A composition comprising: at least one polymer comprising at least one porphyrinic macrocycle covalently linked to at least one conjugated polymer, wherein the porphyrinic macrocycle is metal-free is also presented. Inks can be formulated. Methods of making are provided.
