摘要
以2,2'-联吡啶化合物作为配体,金属钌(Ⅱ)作为受体原子,合成了两种具有不同共轭体系的联吡啶钌(Ⅱ)光敏配合物;并利用红外光谱(IR)和核磁共振氢谱(1HNMR)对各中间产物和光敏配合物的结构进行了表征。研究了这两种光敏配合物电化学及光电性能:两者在可见光区的最大吸收波长分别为539 nm和566nm;两者的带隙计算值分别为1.70 e V和1.55 e V;将两种光敏配合物应用于染料敏化太阳能电池(DSSCs),在100 m W·cm-2(AM1.5)模拟太阳光的照射下,光电转换效率分别达到8.79%和10.16%。
Two photosensitive complexes of different conjugated systems were synthesized,using 2,2’-bipyridine as ligands and ru-thenium ( Ⅱ) as acceptor atom. The two photosensitive complexes and their intermediates were characterized by means of Infrared spectrum(IR) andproton nuclear magnetic resonance spectrometry ( 1HNMR) . The photophysical and electrochemical properties of the complexes were studied respectively:The maximum absorption wavelengths in the visible region were 539 nm and 566 nm;The calculated values of the band gap of the photosensitive complexes were1. 70 eV and 1. 55 eV;The photoelectric conversion efficien-cies of the complexes based DSSCs were 8. 79% and 10. 16% under 100 mW·cm 2(AM1. 5).
