摘要：

TiCl3-induced coupling of meso-formylporphyrins provides cofacial porphyrin dimers such as 1 (M = Cu, Ni) with bridging CH = CH units. These compounds show strong interactions between the porphyrin rings; in the case of M = Ni, the dimer can be easily transformed into the corresponding trans isomer. Similar reactions with beta-formylporphyrins lead to a third type of dimer, a skewed hydroxymethylene-bridged bisporphyrin. These dimeric compounds are models for the photosynthetic reaction center and should facilitate studies on the influence of the dimer geometry on the photophysical properties.
