Nanoseale Integration of Sensitizing Chromophores and Porphyrins with Bacteriophage MS2

摘要

Photosynthetic systems integrate broad-spectrum light-harvesting arrays with reaction centers that generate a charge separation upon photoexcitation. To optimize energy and electron transfer, the distances between the individual components are established with nanometer precision by self-assembling scaffolds of multiple membrane-bound proteins. Numerous investigations have sought to mimic this arrangement of chemical moieties for energy-conversion applications, commonly with porphyrins as the final electron-transfer components. For example, porphyrins have been arranged into nanometer-scale arrays through the use of covalent linkages, hydrogen bonds, and metal coordina-tion.In terms of polymeric structures, dendritic architectures have been used with particular success for the construction of porphyrin-based photocatalytic materials.
