Inprove the efficiency of energy transfer between porphyrin dyes by changing adsorption density

Abstract

In photosynthetic bacteria,the light-harvesting system with regularly-arranged bacteriochlorophylls collects sunlight efficiently.And carried the energy smoothly to the reaction center.We have achieved to develop an interesting porphyrin-clay complex in which the porphyrin molecules densely adsorb on the clay sheets without aggregation.In this work,we focus in the energy transfer reaction between porphyrin dyes on clay.In result,we have enhanced the efficiency of energy transfer by choosing appropriate porphyrins.We found out intermolecular distance affects the efficiency of energy transfer.
