Synthesis and applications of zn-porphyrin based light harvesting materials.

This paper aims on the design and applications of zn-porphyrin based light harvesting assemblies. Porphyrin possess a number of worthwhile applications in light harvesting arrays, molecular wires, catalyst, sensors etc. A number of metals can be used for metallation of porphyrins like cobalt, iron, magnesium, ruthenium, etc. Among all, zinc is the most efficient choice for the light harvesting materials generation based on porphyrins. Zn-porphyrin possess an efficient energy transfer process, it also seems interesting in the visible light absorption and also contributes towards solar cell applications. Due to the high energy demand in the society day by day, everyone is in search of a good light harvesting material which has been accomplished by these porphyrin assemblies. The remarkable properties of zn-porphyrin have attracted the researchers to use it as the building block for the design an excellent light harvesting complex. Various polymeric, monomeric covalently as well as non-covalently linked assemblies based on Zn porphyrins have been a major point of discussion here. [ABSTRACT FROM AUTHOR]
