Molecules of chromophores were attached to appropriate ionic polymers to allow their confinement in desired layers. Good spectral overlap between doner emission and acceptor absorption spectra permits efficient energy transfer in the supra-molecular assembly. Figure 36 summarizes the spectral characteristics of the four photoactive species [184]. The coumarin polymer (Coum-PAH) absorbs in the blue region of the visible spectrum (imax =412 nm), and its emission maximum, 485 nm,... 

The mesoporous materials discussed here comprise silicates and aluminosilicates that are formed from synthesis conditions comparable to zeolites. The main difference with the latter is the use of supra-molecular assemblies of surfactant molecules, e.g. alkyltrimethylammonium ions, as the structure directing agents. Due to the large dimensions of these spherical or cylindrical micelles, the framework of the silicates is not so well crystallized as in the case of zeolites. This causes lower framework stability as well as weaker Bronsted acidity. Upon calcination, large pores of uniform diameter (say 4-10 nm, depending on the surfactants used) become accessible. 

Recently, many studies on the design of metal-containing crystalline supra-molecular assemblies have been carried out [17f,171,21]. A variety of coordination numbers and geometries associated with transition metals as well as various metal-ligand bonding reactions, including M—H---0, O—H---M,...
