Summary. A 1,1'-binaphthol based optically active oligomer 6 with 3,3'-acetylene spacer was prepared from 2,2'-dimethoxy-1,1'-binaphthalene 3 through the palladium-catalyzed Stille coupling reaction. The high optical rotation and CD spectrum varified the main chain chirality of the oligomer. The photophysical properties of 6, absorption, excitation and fluorescent spectra, demonstrated that the oligomer molecule had a conjugated structure, but twisting and rigid conformation would reduce the delocalization along the backbone.
