Self-templating synthesis of a fluorescent porphyrin doped poly(methyl methacrylate) nano-array and its HCl gas sensing properties
Abstract
A highly ordered 5,10,15,20-tetraphenylporphyrin doped poly(methyl methacrylate) nano-array (TPPH2-PMMA NA) has been developed via a facile self-templating synthesis method, which improves the sensitivity of the hydrogen chloride (HCl) gas sensor to the ppm-level. The sensor exhibits visible color variation in gaseous HCl detection. The detection limit is found to be 6.7 ppm.
