Silica/chlorophyll nanocomposites were synthesized for mimicking partly a light-harvesting apparatus of higher plants. The energy transfer between chlorophyll a and b in alkanediol-modified mesoporous silica was observed by fluorescence measurements. To develop an effective immobilization method for the highly efficient energy transfer, chlorophyll derivatives possessing triethoxysilyl groups were also synthesized and grafted onto FSM-type mesoporous silica. In this case, the energy transfer efficiency was higher than that of the former adsorption way.
