A fluorescent and colorimetric sensor based on a porphyrin doped polystyrene nanoporous fiber membrane for HCl gas detection

A fluorescent and colorimetric HCl gas sensor based on the use of the optical probe 5,10,15,20-tetraphenylporphyrin (TPPH₂) contained in a polystyrene nanoporous fiber membrane was facilely fabricated by electrospinning method.
