摘　　要：以1,10-菲洛林为起始原料,通过溴亲电取代反应、席夫碱反应、配位化学反应制得电子受体-配合物L1、L2;辛基咔唑与噻吩通过Witting反应得到含长烷基链的共轭给电子大单体;通过Yamamoto coupling反应制得具有推-拉分子结构的聚合金属配合物P1(Zn)、P2(Co),其结构经GPC、FT-IR、1H-NMR等表征。将目标聚合金属配合物作为染料应用于染料敏化太阳能电池(DSSCs),并研究了光伏性能。结果显示:在模拟太阳光光源(光强为100 mW/cm^(2))下,P1(Zn)、P2(Co)的光电转换效率(PCE)分别为1.97%和1.84%,同时测得P1(Zn)、P2(Co)的热分解温度(T_(d))均超过300℃,热稳定性高。因此,这类含过渡金属(Zn、Co)的聚合物金属配合物作为新型染料应用于DSSCs具有巨大的潜力。Electron acceptor complexes L1 and L2 were prepared by bromoelectrophilic substitution reaction,schiff base reaction and coordination chemical reaction with 1,10-phenolin as starting material.Then the Witting reaction of octylcarbazole and thiophene resulted in conjugated electron-donor monomer with long alkyl chain.Finally,Polymeric metal complexes P1(Zn)and P2(Co)with push-pull molecular structure were prepared by Yamamoto coupling reaction,and their structures were characterized by GPC,FT-IR and 1H-NMR.The target polymer metal complexes were applied as dyes to dye-sensitized solar cells(DSSCs),and the photovoltaic properties were studied.The results show that the photoelectric conversion efficiency(PCE)of P1(Zn)and P2(Co)is 1.97%and 1.84%respectively under the simulated solar light source(100 mW/cm^(2)),and the thermal decomposition temperature(T_(d))of P1(Zn)and P2(Co)is over 300℃,indicating high thermal stability.The result demonstrates transition metal-containing(Zn、Co)polymer metal complexes have great potential as new dyes for DSSCs.
