我们报道了硫原子桥连的逐步光致变色咪唑二聚体的发展。单光子吸收导致产生的有色双自由基物种，迅速重组到初始咪唑二聚体以下的一级反应动力学。双自由基物种的进一步光化学反应产生长寿命的有色物种，其显示分子间二聚化。
We report the development of the stepwise photochromic imidazole dimer bridged by a sulfur atom. The one-photon absorption leads to the generation of the colored biradical species, which rapidly recombines to the initial imidazole dimer following first-order reaction kinetics. The further photochemical reaction of the biradical species produces the long-lived colored species, which shows intermolecular dimerization.
