(Figure Presented) A question of shape: Palladium-catalyzed cross-coupling of borylporphyrins has led to the synthesis of a β-to-β thienylene-bridged porphyrin dimer and two types of trimer (see picture; gray C; white H, pink Ni, yellow S, blue N). The ladderlike trimer exhibits a very large two-photon absorption cross-section (17300 GM) at 800 nm, while that of the triangular trimer is moderate in comparison (8600 GM).
