Research output: Contribution to journalArticlepeer-review


The reinvestigation of photochromic systems (appeared several decades ago) involving hydrogen transfer is described. For instance sulfonyl-substituted 2-benzylpyridine (or benzothiazole) and 2-benzyl-3-benzoylchromones or quinolones undergo thermoreversible photochromic reactions at room temperature. Taking benefit of the chemical or photochemical reactivity of the enol form of the last class of compounds, novel thermoreversible or photoreversible photochromic systems have been designed (1,2-dihydrothioxanthenones and 3-(2-benzylbenzoyl)quinolones respectively), opening promising opportunities for future applications.
