| Abstract [eng] |
Organic molecules with a π -conjugated system have attracted growing interest over recent years, owing to their applications in a wide range of electronic and optoelectronic devices. Electronic and optoelectronic devices using organic materials as active elements involve a charge transport as an essential operation process and hence, require charge-transporting materials. Triphenylamine and carbazole are good precursors for the synthesis of effective hole transporting materials. By a simple one step synthesis method, obtainable star-shaped charge transporting materials with a triphenylamine core and a varying number of different phenylethenyl side arms are solution processable semiconducting materials with extremely high hole mobilities. The newly synthesized organic solution processability, film-forming carbazole based derivatives possessing diarylethenyl fragments are applicable as semiconducting materials in optoelectronic devices, particularly in the perovskite solar cells. Introduction of phenylethenyl fragments into the structure of triphenylamino polymers has been shown to determine better compatibility with the perovskite surface and protect hybrid organic-inorganic perovskite to give highly stable PSCs. |
