合成了一种新型多硫化合物TBDTF,通过核磁和质谱等表征技术建立了其清晰的分子结构,通过紫外-可见光谱对TBDTF和不同物质的量比的TBDTF/C70混合溶液的吸收光谱进行了研究.用荧光光谱表征TBDTF的特征荧光谱.另外,采用不同物质的量比的TBDTF/C70荧光光谱分析TBDTF与C70分子间发生的电荷转移现象.随后将TBDTF和C70等以物质的量比混合制备成光电化学池,进行光电化学性质研究.实验结果表明,TBDTF和C70在溶液中发生了分子间电荷转移.光电化学表征结果表明了TBDTF/C70薄膜在可见光激发下发生了明显的光电转换现象,表明TBDTF是一类优异的多硫给电子分子.“,”We synthesized a novel sulfur-rich compound TBDTF with confirmed structure characterized by NMR and MALDI-TOF mass spectrum.Intermolecular interaction between TBDTF and C70 was studied by UV-Vis and fluorescence spectrum in detail,revealing the charge transfer from TBDTF to C70.Then,we fabricated a photoelectric chemical pool for the study of photoelectric conversion properties of TBDTF/C70.Experiment results disclosed obvious photoelectric effect of TBDTF/C70 film,confirming that TBDTF is an excellent sulfur-rich donor.
