Photophysical Properties on Mobius and Antiaromatic Expanded Porphyrins
Abstract
Expanded porphyrins have come to the forefront in the research field of aromaticity and been recognized as the most appropriate molecular system to study Moebius aromaticity because their molecular topologies can be easily changed and controlled by various methods. Along with this advantage, many efforts have been devoted to the exploration of aromaticity-molecular topology relationship based on electronic structures in expanded porphyrins so that further insight into the aromaticity, very attractive term for chemists, can be provided. In this report, we have investigated the recent progresses of various Moebius (anti)aromatic expanded porphyrins and their photophysical properties in conjunction with the topological transformation between Hoeckel and Moebius aromaticity by various conformational control methods, such as ring fusion and protonation.
