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-29<italic>H</italic>,31<italic>H</italic>-phthalocyanine (VOPcPhO), tris-(8-hydroxy-quinoline)aluminum (Alq₃), and their composites.
