通过钴胺素衍生物的外周修饰合成了B-12复合物-BODIPY二元体。通过紫外-可见光、PL 和瞬态吸收光谱研究了该二元体的光物理性质。报道了三氯化有机化合物 DDT 的可见光驱动脱氯反应。该二元体在 N-2 下表现出有效的脱氯催化作用，反应周转数超过 220。使用二元体在空气下还实现了由滴滴涕和三氯苯甲烷一锅法合成酯和酰胺。
A B-12 complex-BODIPY dyad was synthesized by peripheral modification of cobalamin derivatives. The photophysical properties of the dyad were investigated by UV-vis, PL, and transient absorption spectroscopy. A visible light-driven dechlorination reaction of a trichlorinated organic compound, DDT, was reported. The dyad showed efficient catalysis for dechlorination under N-2 with turnover numbers of over 220 for the reaction. One-pot syntheses of an ester and amide from DDT and benzotrichloride were also achieved using the dyad under air.
