Abstract

Abstract A series of enediyne containing chiral phthalimides were synthesized through Sonogashira coupling reactions. These enediynes were then subjected to thermal Bergman cyclization under vacuum. Polynaphthalenes with pendant chiral groups were obtained and characterized using GPC, IR spectroscopy, NMR spectroscopy, UV–Vis spectroscopy, and photoluminescence analysis. Under properly optimized conditions, the chirality of chiral ...
