Abstract
Phthalocyanine-based organic thin-film transistors (OTFTs) show promise as cannabinoid sensors. This research focuses on enhancing the sensitivity of ZnPc-based OTFTs to THC vapor. By optimizing thin-film morphology, crystal polymorphs, and thickness via physical vapor deposition, a 100x increase in THC sensitivity was achieved. The study highlights the crucial role of deposition conditions and resulting physical film characteristics in device sensitization.
