The co-poly-ynes were obtained in moderate to high yields via Sonogashira coupling reactions and characterized using analytical, spectroscopic and electrochemical techniques and complementary quantum-chemical modelling. The materials show strong optical absorption in the visible region of the spectrum and most also show strong emission with quantum yields in the range of 13-41% relative to rhodamine 6G (R6G). PLED devices based on the co-poly-ynes were prepared and the most promising was measured to have a brightness of up to 1.10 × 104 cd m-2. PSCs based on donor materials incorporating some of the polymers were prepared and demonstrated power conversion efficiencies of up to 0.24%. | Publisher: | Royal Society of Chemistry | Journal: | New journal of chemistry | ISSN: | 1144-0546 | DOI: | 10.1039/d1nj00925g | Rights: | This journal is © The Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2021 The following publication Al-Busaidi, I.
