Abstract

The synthesis of bisporphyrin systems from guest complexation to molecular capsule formation was discussed. The bisporphyrin system was synthesized with different types of spacers linking the porphyrins, being incorporated in cyclic structures. The coupling reaction was found to proceed with a high degree of exo, exo-stereoselectivity, and in reasonable yields. It was found that in case of free-base porphyrin, complexed within Zn₂(5a), an unexpected photophysical result was obtained which suggested that the photoinduced energy transfer occurred from guest to host.
