10-bis(1,5-diphenylpenta-1,4-diyn-3-ylidene)-9,10-dihydroanthracenes (BDPPD-DHAs) carrying polar organic functional groups was synthesized through Sonogashira cross-coupling reactions. The structural and electronic properties of these BDPPD-DHA derivatives were investigated by single crystal X-ray diffraction, UV-Vis absorption, and fluorescence spectroscopic analyses. It was found that the incorporation
