Title:
SUPRAMOLECULAR COMPLEX OF PYRIDYLNAPHTHALENEDIIMIDE WITH ZINC PORPHYRIN DENDRIMER HAVING MULTIPLICITY OF ARTIFICIAL PHOTOSYNTHETIC REACTION CENTER
Document Type and Number:
WIPO Patent Application WO/2005/087846
Kind Code:
A1
Abstract:
A light energy conversion system having a multiplicity of artificial photosynthetic reaction centers and exhibiting a high light collection capability and charge separation capability, constructed by the use of a zinc porphyrin dendrimer supramolecular complex formed with the use of a coordinate bond. Using a zinc porphyrin dendrimer as a spherical zinc porphyrin oligomer, there was constructed a supermolecule with pyridylnaphthalenediimide. With respect to the zinc porphyrin dendrimer/pyridylnaphthalenediimide supermolecule, when photoexcitation of the zinc porphyrin was realized, a state of charge separation was generated by photoinduced electron transfer and the life thereof was as strikingly long as 830 microseconds.
