Modulating the Photoluminescence of Bridged Silsesquioxanes Incorporating Eu(3+)-Complexed n,n '-Diureido-2,2 '-bipyridine Isomers: Application for Luminescent Solar Concentrators

Two new urea-bipyridine derived bridged organosilanes (P5 and P6) have been synthesized and their hydrolysis-condensation under nucleophilic catalysis in the presence of Eu(3+) salts led to luminescent bridged silsesquioxanes (M5-Eu and M6-Eu). An important loading of Eu(3+) (up to 11%(w)) can be ob...
