摘要: Four spiro[fluorene-9,9′-xanthene] (SFX) derivatives, SFX-TAD, SFX-TCz, SFX-TPTZ and SFX-MeOTAD have been synthesized for use as hole-transport materials fully characterized by 1H/13C NMR spectroscopy, mass spectrometry, XRD DSC. Their thermal, optical electrochemical properties were investigated. The of different substituents affects the highest occupied molecular orbital (HOMO) energy level proving versatility central core towards facile low-cost preparation spiro-hole-transport materials. Among SFX was employed hole-transporting material (HTM) performance tested in perovskite solar cells with device architecture glass/FTO/compact TiO2/mesoporous Al2O3/CH3NH3PbI3−xClx/HTM/Au. gave a comparable efficiency to spiro-MeOTAD, demonstrating great potential family cost effective versatile hole conductors facilitating commercialization (PSCs).
