Patent ID: 10454034

Abstract:
Provided is a hexabenzocoronene-based compound and a donor: acceptor layer having this compound. Also provided are processes for manufacturing this compound and to a photovoltaic cell having at least one hexabenzocoronene-based compound. The hexabenzocoronene-based compound has following formula I: wherein R1, R3, R4 and R6 are independently from each other chosen among a carboxylic (—COOH) group, a cyano (—C≡N) group, an isocyano (—N+≡C−) group, a cyanate (—O—C≡N) group and a —F group, and R2 and R5 are, independently from each other, chosen among a poly(3-oxypentylthiophene) (P3OPT) substituent and a poly(3-hexylthiophene) (P3HT) substituent.
