A set of novel hole-transporting materials (HTMs) based on π-extension through carbazole units was designed and synthesized via a facile synthetic procedure. The impact of isomeric structural linking on their optical, thermal, electrophys., and photovoltaic properties was thoroughly investigated by combining the exptl. and simulation methods. Ionization energies of HTMs were measured and found to be suitable for a triple-cation perovskite active layer ensuring efficient hole injection. New materials were successfully applied in perovskite solar cells, which yielded a promising efficiency of up to almost 18% under standard 100 mW cm-2 global AM1.5G illumination and showed a better stability tendency outperforming that of 2,2′,7,7′-tetrakis-(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene. This work provides guidance for the mol. design strategy of effective hole-conducting materials for perovskite photovoltaics and similar electronic devices. In the part of experimental materials, we found many familiar compounds, such as 3,6-Dibromo-9H-carbazole(cas: 6825-20-3Computed Properties of C12H7Br2N)
3,6-Dibromo-9H-carbazole(cas: 6825-20-3) is used as a pharmaceutical intermediate, and also an important intermediate of synthesizing optoelectronic materials. It has been used as a reagent in the synthesis of P7C3-A20 which is a potent neuroprotective agent.Computed Properties of C12H7Br2N
