A new generation of soluble phenothiazinyl merocyanine substituted polyacetylenes can be readily synthesized by rhodium-catalyzed polymerization of the corresponding 3-ethynyl phenothiazines, accessible by Sonogashira coupling and Knoevenagel condensation. UV/Vis and fluorescence spectroscopy of 7-acceptor-substituted phenothiazinyl polyacetylenes reveal that these polyacetylenes with conjugatively ligated merocyanines are luminescent in solution with positive emission solvatochromism and, in some cases, with distinct solid-state luminescence.
新一代可溶性吩噻嗪基部花菁取代的聚乙炔可以通过铑催化相应的3-乙炔基吩噻嗪的聚合反应轻松合成，而这些3-乙炔基吩噻嗪可通过Sonogashira偶联和Knoevenagel缩合反应制得。7-受体取代的吩噻嗪基聚乙炔的紫外/可见光谱和荧光光谱表明，这些带有共轭连接部花菁的聚乙炔在溶液中发光，具有正发射溶剂化显色现象，并且在某些情况下具有明显的固态发光。
