Abstract
•Nano-porous structures of VTTBNc were successfully fabricated and used in the humidity sensors as active sensing layer.•By simply controlling the spin rate during spin coating, the optimum sensor showed good humidity sensing properties.•Nano-porous structures of VTTBNc a potential candidate for fabricating state-of-the-art humidity sensors.
A novel structured of nanoporous vanadyl 2,11,20,29-Tetra Tert-Butyl 2,3 Naphthalocyanine (VTTBNc) films were prepared by template-assisted method. The structure and morphology of the fabricated VTTBNc nanostructures were studied by field emission scanning electron microscopy (FESEM) and micro-Raman spectroscopy. The VTTBNc nano-porous films showed a potential application in humidity sensors.
