## Abstract Several (multiply) iodinated squarylium cyanine dyes of type **1** and **8** (see __Scheme__ and __Table__), derived from 1,3‐benzothiazole and 6‐iodo‐1,3‐benzothiazole, were synthesized as potential new photosensitizers, with absorptions in the 700‐nm region. Their ability to generate
The quinone-linked porphyrin dimer 2 was prepared by the coupling of dipyrrolic intermediates. Compound 2, as a dilute solution in toluene, shows no detectable fluorescence when irradiated at 407 nm. Complex photosynthetic models containing two or more porphyrins with covalently attached acceptors
