我们合成了7种新型的含吩噻嗪（PTZ）基序的有机共聚炔P1-P7，并对其光电性能和在聚合物发光二极管和聚合物太阳能电池（PLED/PSC）中的应用进行了评价。通过Sonogashira偶联反应以中等到高的产率获得了共聚炔，并使用分析、光谱和电化学技术以及互补的量子化学建模进行了表征。这些材料在光谱的可见光区显示出强的光吸收，并且大多数还显示出强的发射，相对于罗丹明6 G（R6 G），量子产率在13-41%的范围内。制备了基于共聚炔的PLED器件，测得最有希望的器件亮度高达1.10 x 10（4）cd m（-2）。制备了基于掺入一些聚合物的供体材料的PSC，并证明了高达0.24%的功率转换效率。
We present the synthesis and characterization of seven new organic co-poly-ynes P1-P7 incorporating the phenothiazine (PTZ) motif and evaluate their optoelectronic properties and performance in polymer light-emitting diodes and polymer solar cells (PLEDs/PSCs). 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 x 10(4) 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%.
