Precursor molecule (R)-6,6'-bis(triethoxysilylethen-2-yl)-2,2'-di(methoxyethoxymethyloxy)-1,1'-binaph-thyl (R-2) was synthesized by Pd-catalyzed Heck reaction of (R)-6,6'-dibromo-2,2'-di(methoxyethoxymethyloxy)-1,1'-binaphthyl (R-1) intermediate with vinyltriethoxysilane. The hydrolysis and polycondensation of the precursorR-2 produced the corresponding xerogel. Both precursor and xerogel were analysed by NMR, FTIR, UV, CDspectra, fluorescent spectroscopy, polarimetry and elemental analysis. The precursor and xerogel can emit strongblue fluorescence and are expected to have a potential application in the separation of chiral molecules as fluo-rescent sensor. The precursor exhibits strong Cotton effect in its circular dichroism (CD) spectrum indicating ahighly rigid structure.
