摘要
Multilayer films composed of inorganic colloids (alpha-zirconium phosphate or HTiNbO5) and organic polycations can be grown in almost any desired sequence on surfaces by electrostatic self-assembly. Control of the edge chemistry of the anionic sheets is essential to the preparation of well organized monolayers and multilayers. Examples;are given of layer sequences that incorporate electron donors and accepters, which undergo photoinduced electron transfer reactions across inorganic spacer layers, similar stacking sequences can be used to couple light harvesting assemblies, containing energy donors and acceptors, to electron donor-acceptor dyads.
