Synthetic explorations towards polycyclic bisporphyrinfunctionalized 'host' systems

Molecular architectures containing in-built porphyrin components continue to attract attention as host-guest components and in various aspects of energy and electron transfer. Supramolecular systems possessing various flexible and semi-flexible linkers between two porphyrin rings have been synthesized and employed in host-guest studies. Here we report the results of our synthetic efforts to prepare novel space separated bis-porphyrin host system of type 1 (Figure 1).[1] This system is more flexible than previously reported bisporphyrins[2], but still directing the functionalities towards the same side of the molecule. For synthetic purpose, modern green chemistry methodologies in particular microwave irradiation[3] and high-speed vibrational milling have been employed.
