Abstract
The Heck coupling reaction of vinyl-terminated double four-ring siloxane cages (octavinylsilsesquioxane) with aromatic bromide monomers (4,4′-dibromobiphenyl, 1,4-dibromonaphthalene, 2,6-dibromonaphthalene and 1,2-bis(4-bromophenyl)-1,2-diphenylethene) was used to construct a class of luminescent nanoporous inorganic-organic hybrid polymers (PS-n). The structures of these polymers were confirmed by solid state 13C CP/MAS and 29Si MAS NMR spectra, as well as Fourier transform infrared spectroscopy (FTIR). The results identify polymers with Brunauer-Emmett-Teller (BET) surface areas of up to 685 m2 g-1. The luminescence properties of these polymers were utilized for picric acid detection. Furthermore, PS-1-n (n = 6, 12, 24, 48 or 72 h) samples polymerized for different lengths of time were investigated for their energy transfer behaviour with Coumarin 6.
