中文摘要	four new solution-processible small-molecular platinum(ii)bis(aryleneethynylene) complexes consisting of benzothiadiazole as the electron acceptor and triphenylamine and/or thiophene as the electron donor were conveniently synthesized and characterized by physicochemical and computational methods, and utilized as the electron-donor materials in the fabrication of solution-processed bulk heterojunction (bhj) solar cells. the effect of different electron-donor groups in these small molecules on the optoelectronic and photovoltaic properties was also examined. the optical and time-dependent density functional theory studies showed that the incorporation of stronger electron-donor groups significantly enhanced the solar-absorption abilities of the complexes. these molecular complexes can serve as good electron donors for fabricating bhj devices by blending them with the [6,6]-phenyl-c71-butyric acid methyl ester (pc70bm) as the electron acceptor. the best power conversion efficiency of 2.37% was achieved with the open-circuit voltage of 0.83 v, short-circuit current density of 7.10 macm(-2) and fill factor of 0.40 under illumination of an am 1.5 solar-cell simulator. the spin-coated thin films showed p-channel field-effect charge transport with hole mobilities of up to 2.4 x 10(-4) cm(2) v-1 s(-1) for these molecules. the present work illuminates the potential of well-defined organometallic complexes in developing light-harvesting small molecules for efficient power generation in organic photovoltaics implementation.
