Abstract

Porphyrin-fluorene conjugates bridged by ethynylene were synthesized through Pd-catalyzed cross-coupling reaction. These molecules showed strong nonlinear absorption when measured using a nanosecond Z-scan method. The largest effective two-photon absorption cross-section was observed for trisporphyrin as 2.7 × 105 GM at 760 nm, which was 10 times larger than that obtained for monoporphyrin.
