Photochromic compounds are promising for a variety of applications, including molecular solar thermal (MOST) energy storage. The release step and cyclability critical issues to be addressed the development this technology. We report herein synthesis characterization two diarylethene molecules featuring one (1) or (2) pyridine groups as protonatable moieties. Upon UV irradiation, both undergo cyclization reaction from open form (OF) closed (CF). Both CF stable few days in acetonitrile, addition acid leads 600 1500-fold acceleration ring-opening reaction, even catalytic amounts. A kinetic model is proposed simulate elucidating contribution each kinetics evidencing importance control over protonation thermodynamic equilibrium. Data fitting rates elementary steps turnover numbers (TON). Following complete cycle, neutralization by an equivalent amount base allowed further cycles. This study represents significant advancement on-demand triggering energy-releasing diarylethenes future MOST applications.
