摘要： The invention concerns spirobifluorene compounds having the following structure:
wherein R1 and R3 are both ring structures containing one or more aromatic or heteroaromatic rings, R1 and R3 not both being phenyl at the same time, and the -R1-(R2)n and -R3-(R2)n structures are selected from the group consisting of:
(1) phenyl, (2) biphenyl, (3) naphthyl, (4) triphenylamine; (5) dibenzofuran joined through its ring position 2 to a N atom of compound I; (6) triphenylamine vinyl; (7) dibenzofuran joined through its ring position 1 to a N atom of compound I; (8) napthalene-benzofuran; (9) 4-pyridinyl-phenyl; (10) 2,2-bithienyl; (11) spirofluorenoxanthene; and (12) fused thienyl,
wherein each R2 substituent where present is methoxy.
The spirobifluorene compounds are organic hole transporting materials (HTMs) useful to increase power conversion efficiency (PCE) of perovskite solar cells (PSCs).
