Abstract

Abstract The synthesis and photophysical properties are described for a series of porphyrin, phthalocyanine and pyrazinoporphyrazine derivatives which bear four or eight peripheral fluorenyl substituents as antennae. Representative examples are 5, 10, 15, 20-tetra (9, 9- dihexyl-9H-fluoren-2-yl) porphyrin (2), 5, 10, 15, 20-tetrakis [4-(9, 9-dihexyl-9H-fluoren-2-yl) phenyl] porphyrin (3), 2, 3, 9, 10, 16, 17, 23, 24-octakis (9, 9-dihexyl-9H-fluoren-2-yl)-29H, ...
