Abstract
This special issue, themed for Porphyrins and Porphyrinoids, was initiated from the “Schulich Summer School Conference 2014” which was held at Technion-Israel Institute of Technology. In the conference, all participants could spend valuable time to discuss about macrocyclic metal coordination complexes including porphyrin-based materials. I would like to express thanks to Prof. Zeev Gross and Jonathan L. Sessler for their kind invitation to the “Schulich Summer School Conference”. In the conference, I could meet Prof. Ehud Keinan as Editor-in-Chief of this journal, who gave me an honorable chance to edit this special issue. Porphyrins and chlorophylls are fundamental and ubiquitous pigments in natural systems. Porphyrins perform many essential functions in biological systems, such as oxygen transport, active sites in enzymes, and light harvesting. The porphyrin-based functional nanodevices in biosystems provide great motivations for the design of biomimetic functional materials, because the efficiency of biosystems is incomparably higher than artificial ones. Porphyrins have many distinct photophysical and electrochemical properties due to the expanded π-conjugation. Various metal ions can be coordinated into the porphyrin center. Thus, the physical and chemical properties of porphyrins can be tuned by metal coordination. Owing the symmetry of porphyrin skeleton, porphyrins are often utilized as a building block for the construction of functional supramolecular architectures. Some porphyrin derivatives are used for biomedical applications, such as photodynamic therapy and diagnostics. This special issue covers all aspects of porphyrins and porphyrinoids related chemistry, including photophysics, supramoleuclar chemistry, and biomedical applications. I would like to express sincere thanks to all authors and reviewers for their efforts and valuable contribution to this special issue. Finally, I would like to thank Prof. Ehud Keinan for inviting me to serve as guest editor of this special issue and to Dr. Brian Johnson of Wiley-VCH, for his kind and continuous support to publish on time. 1 Woo-Dong Jang Yonsei University Guest Editor
