作为一项研究的一部分，针对设计良好的催化体系的基础上，疏水性维生素B-12，七甲基钴氰酸酯高氯酸盐，我们描述了各种纳米材料的制备使用的维生素B-12衍生物和光敏剂。实例包括维生素B-12-超支化聚合物（HBP）、含维生素B-12衍生物的人血清白蛋白（HSA）、维生素B-12-二氧化钛混合催化剂、维生素B-12-Ru复合物组合体系和维生素B-12-玫瑰红组合体系。这些仿生材料具有作为催化体系的潜力，用于降解有机卤化物污染物和用于在UV或可见光照射期间经由自由基中间体进行分子转化，并且提供了在绿色化学方面引起极大兴趣的各种应用。
As part of a study directed toward design of good catalytic systems based upon a hydrophobic vitamin B-12, heptamethyl cobyrinate perchlorate, we describe the preparation of various nanomaterials using the vitamin B-12 derivative and photosensitizers. Examples include vitamin B-12-hyperbranched polymers (HBPs), human serum albumin (HSA) containing vitamin B-12 derivatives, a vitamin B-12-titanium dioxide hybrid catalyst, a vitamin B-12-Ru complex combined system, and a vitamin B-12-rose bengal combined system. These bioinspired materials have the potential as catalytic systems for the degradation of organic halide pollutants and for molecular transformations via radical intermediates during irradiation by UV or visible light, and offer a variety of applications that are of great interest in terms of green chemistry.
