Organically capped metal oxide nanostructures offer an interesting combination of chemical and physical sensitivities. In particular, the sensitivity to light and to gases have been shown to cooperate in order to strength each other. In this paper, we studied the properties of pyrene tetratopic ligands (PTL) and ZnO nanorods. After structural and morphological characterizations of the nanohybrid materials, mutual cooperation of selectivity to visible light and to volatile organic compounds (VOCs) is investigated measuring the surface potential distribution with a scanning kelvin probe. Results show the photo assisted selective response to donor compounds such as triethylamine.
