Solvent-dependent Photoreactions of Porphyrin-Spiropyran Dyad: Ring-opening or Protonation

摘要

Porphyrin (Por) has a strong absorption characteristics in the range of sunlight due to a chemical structure of high conjugation and rigidity, good redox properties, and well-established synthetic methods. Accordingly, porphyrin-based multicomponent compounds have been investigated in a variety of applications such as artificial light-harvesting antenna, molecular energy storage devices, solar cells, optoelectronic switches, and photodynamic therapy.
