Abstract

The synthesis and characterization of two related families of star-shaped thiophene-containing hole-transporting materials (HTMs) based on fused tetrathienoanthracene and nonfused tetrathienylbenzene cores are reported. All of them are endowed with four terminal (4,4'-dimethoxy)diphenylamino groups that are either linked directly to the core or showed a different type of bridges (i.e., thiophene-phenyl or phenyl rings). The novel HTMs are tested in mixed-ion perovskite (Cs0.1FA0.74MA0.13PbI2.48Br0.39) solar cells, and power conversion efficiencies of up to 18.8% are measured under 1 sun irradiation, comparable with the efficiency obtained for the reference cell using 2,2',7,7'-tetrakis(N,N'-di-p-methoxyphenylamine)-9,9'-spirobifluorene as an HTM.
