摘要

In this work, four tetraphenylethylene (TPE)-centered hole transport materials (HTMs), with 2,7- or 3,6-substituted carbazole derivatives as periphery groups are deliberately synthesized and characterized. Their photophysical properties, energy levels, and photovoltaic performances are systematically investigated, and their performances as HTMs are discussed with respect to the different substituent positions on the carbazole moiety. It is interesting to find that the TPE-based HTMs with 2,7-carbazole substituents rival the 3,6-carbazole substituents in hole mobility and hole extraction ability. A high power conversion efficiency of up to 16.74% is achieved for the devices based on the 2,7-carbazole periphery arms, which is even higher than the one of the "star" HTM Spiro-OMeTAD (2,2-7,7-tetrakis(N,N'-diparamethoxy- phenylamine 9,9'-spirobifluorene) under the same conditions. As far as we know, this is the highest efficiency achieved in tetraphenylethylene derivatives.
