Kinetics of Coloration in Photochromic Organoammonium Polyoxomolybdates

INORGANIC CHEMISTRY, 48(2), 574–580.

By: R. Dessapt *, M. Collet*, V. Coue n, M. Bujoli-Doeuff*, S. Jobic *, C. Lee n, M. Whangbo n

MeSH headings : Color; Hydrogen / chemistry; Hydrogen Bonding; Kinetics; Models, Chemical; Molybdenum / chemistry; Organometallic Compounds / chemistry; Photochemical Processes; Quantum Theory; Quaternary Ammonium Compounds / chemistry; Spectrophotometry, Ultraviolet
TL;DR: The rates of coloration, which increase in the order 1 < 3, 2 < 4, are related to the decrease in the concentration of reducible Mo(6+) centers with irradiation time and follow a second-order reaction law because the event of light absorption at a reducibleMo( 6+) site does not necessarily coincide with that of the N(+)-H bond breaking in the N-H...O hydrogen bond associated with the Mo(5+) site.
