## Abstract The linear conjugated polymer based on the 5,5β²βpositions of chiral 1,1β²βbinaphthyl shows strong greenβblue fluorescence with high fluorescence quantum efficiency due to the extended __Ο__βelectronic structure between the chiral repeating unit and the 2,2β²βbipyridyl conjugated linker un
