金属卟啉在氧化电子转移体系中具有良好的前景。本文报道了通过Fe(III)meso-四(4-羧基苯基)卟啉氯化物与磁性纳米粒子之间的共价键合,可控合成可磁性分离的金属卟啉。合成的磁性可分离金属卟啉对酸性橙子7的脱色率为69.02%。用永磁棒可以很容易地从反应液中回收,重复使用三次后,其脱色活性仍保持在95.64%。稳定的循环性能归因于金属卟啉分子与小尺寸、非聚集且自由分散的纳米颗粒之间的共价键连接。
Metalloporphyrins possess promising prospect in the oxidative electron-transfer systems. We report here the controllable synthesis of magnetically separable metalloporphyrin via a covalent bonding between Fe(III) meso-Tetra (4-carboxyphenyl) porphine chloride and magnetic nanoparticles. The as-synthesized magnetically separable metalloporphyrin showed 69.02% decoloration efficiency for Acid orange 7. It could be readily recovered from the reaction solution by using a permanent magnetic bar and its decoloration activity remained 95.64% after three cycles of repetitive uses. The stable recycle performance was ascribed to the covalent bond linkage between the metalloporphyrin molecules and the small sized, non-aggregation, and freely dispersed nanoparticles.
