摘要
The use of benzothiazole as an electron-withdrawing group allows obtaining the fastest thermal isomerisation kinetics reported heretofore for neutral azo dyes (70 mu s at 298 K). These green light activatable molecules are valuable candidates as molecular photo-switches since they tolerate thousands of working cycles with no sign of fatigue.
