Two new electron-rich molecules, 2,3,4,5-tetra[4,4′-bis(methoxyphenyl)aminophen-4“-yl]-thiophene (H111) and 4,4′,5,5′-tetra[4,4′-bis(methoxyphenyl)aminophen-4”-yl]-2,2′-bithiophene (H112), which contain thiophene cores with arylamine side groups, are reported. When used as the hole-transporting mate...
