Self-assembled composite materials of porphyrins for optoelectronics

Construction of molecular architectures based on aggregation or self-association for controlled size and shape is a simple and convenient method [1-5]. Of particular interest are efficient energyand electron-transfer processes [6-8], which are very related to the molecular assembly in natural photosynthetic system, providing better understanding of photofunctional molecular architectures. These fundamental researches of such organic materials also entail synthetic and photophysical processes ofmolecular aggregates with nanometer scales since their optical properties significantly differ from those of monomeric species [1, 2].
