Synthesis and characterization of electron donor/acceptor subphthalocyanine derivatives and porphyrin metal complexes

Abstract

Multicomponent electron-donor acceptor systems incorporating supramolecules such as porphryins, phthalocyanines, subphthalocyanines, and perylenes have gained utmost importance in various fields of optoelectronics. Subphthalocyanines are unique, non-planar, aromatic supramolecules which have recently emerged as a platform for novel electron acceptors as they show great potential in photosynthetic systems. Subphthalocyanine is an excellent electron acceptor, when covalently linked to other electron donor species through the axial substitution and executes fast photoinduced electron transfer. The axial approach to a synthesis is advantageous in the sense that the electronic characteristics of the subphthalocyanine macrocyle are preserved. Subphthalocyanine derivatives prepared in this study are expected to have outstanding tunable properties for the development of artificial photosynthetic systems and various molecular electronic devices. This dissertation will center on the synthesis, characterization of various donor-acceptor conjugates of subphthalocyanine.
