Compositional engineering of the pi-conjugated small molecular VOPcPhO : Alq3 complex to boost humidity sensing

Abstract
This study exhibits a solution-processed organic semiconductor humidity sensor based on vanadyl 2,9,16,23-tetraphenoxy-29H,31H-phthalocyanine (VOPcPhO), tris-(8-hydroxy-quinoline)aluminum (Alq3), and their composites.
