Abstract
The vibrationally resolved pyrene fluorescence probe method was once popular but now languished, because the vibrationally resolved patterns of pyrene with limited sensitivity and concentration independence have not been updated for over 50 years. During our investigation on the polymer interdiffusion of a latex film, we found a pyrene acylhydrazone whose vibrationally resolved fluorescence pattern contradictory to those reported in pyrene and most pyrene derivatives. The pyrene acylhydrazone has sensitive concentration- and polarity-dependent fluorescence spectra (the sensitivity on polarity is at most 26 times higher than the old vibrationally resolved patterns), and the sensitivity well remains when it is copolymerized in a polymer. The vibrationally resolved spectrum of this pyrene acylhydrazone is a powerful fluorescence probe, which would be as useful as the pyrene excimer probe nowadays popular.
