Résumé
Lutetium bisphthalocyanine (LuPc) is a well-established molecular semiconductor, yet its fluorinated derivatives remain largely unexplored. In this work, we investigate the lutetium octafluorosubstituted bisphthalocyanine complex, Lu(FPc). The complex was synthesized both directly from 4,5-difluoro-1,2-dicyanobenzene and via the metal-free octafluorophthalocyanine precursor HFPc, and characterized by mass spectrometry and optical spectroscopy. Drop-cast films of Lu(FPc) were fabricated and their electrical properties evaluated. Additionally, we examined the response of these resistors to ammonia. Bilayer heterojunctions combining Lu(FPc) with its nonsubstituted analogue, LuPc, were also prepared. Notably, Lu(FPc) resistors and Lu(FPc)/LuPc heterojunctions exhibit opposite responses to NH, positive and negative, respectively. These findings provide new insights into structure-property relationships in phthalocyanine-based semiconductors.
