| Research Abstract |
The amphiphilic liquid crystalline diblock copolymer afforded a highly ordered cylindrical phase segregated nanostructure was used as a template for the site-specific arrangement of the functional molecules, which were regio-specifically introduced at the junction between a hydrophilic and a hydrophobic segments, at the phase segregation interface. The porphyrin units at the junction of diblock copolymer were accumulated at the cylindrical interface to give the circular and/or cylindrical porphyrin arrays similar to the chlorophyll arrays in the natural light harvesting antenna. The thin film of this copolymer generated larger photocurrent than that of the simple mixture of amphiphilic diblock copolymer without porphyrin unit with equal amount of ZnTPP.
