Efficient energy and electron transfer between donor and acceptor chromophores in aluminophosphate hybrid materials

The first organic-inorganic hybrid materials (OIHMs) having one or a combination of two chromophores in different ratios are obtained from the aryl phosphonic acid and aluminum lactate via sot gel process The structures of these OIHMs are analyzed by the Al-27 and P-31 NMR The fluorescence resonance energy transfer (FRET) as well as photoinduced electron transfer (PET) between donor and acceptor chromophores in these hybrid materials have been investigated and the efficiencies can be up to 97 and 93%, respectively.
