Quantitative Analysis for a Color-Change of Humidity Indicator by Microscopic Absorption Spectrometry

A sensitive and easily distinguishable cobalt-free humidity indicator of porphyrin-silica gel-MgCl2 composite was prepared from pH-induced spectra changeable tetraarylporphyrin, silica gel (SiO2), and MgCl2. The pH change arose from proton release under dry conditions, and proton capture under humid...
