Abstract
Meso-? bridged extended porphyrins substituted with long aliph. chains were synthesized and fully characterized. Two different synthetic strategies were tested to obtain the target structures. The synthetic steps were optimized to obtain scalable routes for the prodn. of sufficient quantities of ?-extended porphyrins for material science studies. The porphyrins were obtained either as free bases or complexed with NiII or CuII. UV-visible spectroscopy and polarized light microscopy was used for the anal. of the material properties of the ?-extended porphyrins. The results obtained with the authors' compds. are not compatible with the results reported in the literature. [on SciFinder(R)]
