1多功能咔咯配合物的合成与应用进展显示文摘咔咯(Corrole)是由4个吡咯共轭相连而形成的新型卟啉类大环配合物,它们能稳定结合具有较高氧化态的金属离子,所形成的金属配合物具有比较独特的光化学、电化学、光物理和光生物性质。研究表明,咔咯是一类非常重要的多功能配合物,它们在精细化学品领域具有广阔的应用前景。对咔咯配合物的主要合成方法、配合物用作精细化工催化剂、燃料电池电极催化材料、抗肿瘤光敏剂、电化学传感器和非线性光学材料等方面的研究和应用作了综述。朱卫华 赵晓锋 王晓红 吴元钊 欧忠平 2010化学试剂2010,32,2:7
2Appended corrole manganese complexes:Catalysis and axial-ligand effect显示文摘A series of N-base appended corroles and their manganese complexes were synthesized and their binding constants with three different nitrogenous ligands,triethylamine,N-methylimidazole and pyridine,were evaluated by spectroscopy.Kinetic studies indicated that the presence of appended Ndonor ligands may cause a significant enhancement of the rate of oxygen atom transfers(OAT) from(oxo)manganese(V) corrole to alkene,and the stronger axial ligand binding has impact on the rate of the oxidation reaction.Turnover frequency(TOF) for the catalytic oxidation of alkenes by appended manganese corroles varies with the following ligand order:acetamido < pyridyl < imidazolyl.The influence of the external axial ligands on the catalytic epoxidation was investigated by using appended acetamido manganese corrole as catalyst,with the results revealing that N-methylimidazole gave the best enhancement on the yields of total oxidation products among the investigated nitrogenous ligands.Nga-Chun Ng Mian HR Mahmood Chi-K.Chang Hai-Yang Liu Fei Yam Lam-Lung Yeung 2014Chinese Chemical Letters2014,25,4:3
3Metallocorrole-based porous organic polymers as a heterogeneous catalytic nanoplatform for efficient carbon dioxide conversion显示文摘Metallocorrole macrocycles that represent a burgeoning class of attractive metal-complexes from the porphyrinoid family,have attracted great interest in recent years owing to their unique structure and excellent performance revealed in many fields,yet further functionalization through incorporating these motifs into porous nanomaterials employing the bottom-up approach is still scarce and remains synthetically challenging.Here,we report the targeted synthesis of porous organic polymers(POPs)constructed from custom-designed Mn and Fe-corrole complex building units,respectively denoted as CorPOP-1(Mn)and CorPOP-1(FeCl).Specifically,the robust CorPOP-1(Mn)bearing Mn-corrole active centers displays superior heterogeneous catalytic activity toward solvent-free cycloaddition of carbon dioxide(CO_(2))with epoxides to form cyclic carbonates under mild reaction conditions as compared with the homogeneous counterpart.CorPOP-1(Mn)can be easily recycled and does not show significant loss of reactivity after seven successive cycles.This work highlights the potential of metallocorrole-based porous solid catalysts for targeting CO_(2) transformations,and would provide a guide for the task-specific development of more corrole-based multifunctional materials for extended applications.Yanming Zhao Yunlei Peng Chuan Shan Zhou Lu Lukasz Wojtas Zhenjie Zhang Bao Zhang Yaqing Feng Shengqian Ma 2022Nano Research2022,15,2:0
