聚（苯撑乙炔-氰基乙烯苯撑）共聚物合成及光伏性能

Synthesis and photovoltaic devices performance of poly（phenylene -bisethynylene）-alt-（（cyano-styryl）benzene）

利用钯催化剂（Pd（PPh3）2C12）和相转移催化剂（PTC），采用Heck交叉偶联缩聚反应合成了聚（苯撑乙炔-氰基乙烯苯撑）共聚物（C12-PPE-DCNTB），比较了聚合物的紫外吸收光谱和荧光光谱特征。以ITO为阳极，Ba／A1为阴极，制备了构型为IT0，PEDOT-PSS／MEH-PPV＋C12-PPE-DCNTB（1／1，w／w）／Ba／A1的本体异质结器件，初步讨论了活性层的光物理特征及器件的光伏性能。

poly（phenylene-bisethynylene）-alt-（（cyano-styryl）benzene） alternating copolymer containing electron donor and electron acceptor units was synthesized by cross-coupling polycondensation with Pd（PPh3）2C12 and phase transfer catalysts. The UV-Vis and PL of copolymer were measured respectively. Photovoltaic devices based on the configuration of ITO/PEDOT-PSS/C12-PPE-DCNTB/Ba/A1 were fabricated. The photophysics of active layer, photovoltaic performance of the devices was also discussed.
