The pyrolysis of the catalyst, which is commonly involved in the preparation of ORR catalytic systems, is not necessary. Compared to monomeric metalloporphyrins, the framework shows enhanced ORR catalytic activity, presumably due to the porous and conjugated

  开发用于氧气还原反应（ORR）的高效催化剂对于许多新兴技术至关重要，以应对能源和环境危机。在这里，我们报告炔复分解聚合协议以合成包含互连的ORR催化中心的基于共轭微孔金属卟啉的框架。骨架和炭黑的简单复合物在酸性和碱性条件下均通过四电子还原机理表现出出色的ORR电催化活性和特异性。催化剂的热解通常不需要进行ORR催化体系的制备。与单体金属卟啉相比，该骨架显示出增强的ORR催化活性，这可能是由于骨架结构具有多孔性和共轭性，这样可以更好地暴露催化活性位点，并实现有效的电子/质量传输。更重要的是，复合电催化剂显示出比市售Pt / C和金属卟啉单体优异的耐久性和甲醇耐受性。考虑到共轭微孔聚合物的高度结构可调性，可以想象的是，这种非热解方法可以系统地探索基于有机骨架的ORR催化剂的结构-活性关系，并最终导致开发出具有成本效益的替代品。铂/碳。

• Mechanism and Driving Force of NO Transfer from <i>S</i>-Nitrosothiol to Cobalt(II) Porphyrin:  A Detailed Thermodynamic and Kinetic Study

  The thermodynamics and kinetics of NO transfer from S-nitrosotriphenylmethanethiol (Ph3CSNO) to a series of alpha,beta,gamma,delta-tetraphenylporphinatocobalt(II) derivatives [T(G)PPCoII], generating the nitrosyl cobalt atom center adducts [T(G)(PPCoNO)-N-II], in benzonitrile were investigated using titration calorimetry and stopped-flow UV-vis spectrophotometry, respectively. The estimation of the energy change for each elementary step in the possible NO transfer pathways suggests that the most likely route is a concerted process of the homolytic S-NO bond dissociation and the formation of the Co-NO bond. The kinetic investigation on the NO transfer shows that the second-order rate constants at room temperature cover the range from 0.76 x 10(4) to 4.58 x 10(4) M-1 s(-1), and the reaction rate was mainly governed by activation enthalpy. Hammett-type linear free-energy analysis indicates that the NO moiety in Ph3CSNO is a Lewis acid and the T(G)PPCoII is a Lewis base; the main driving force for the NO transfer is electrostatic charge attraction rather than the spin-spin coupling interaction. The effective charge distribution on the cobalt atom in the cobalt porphyrin at the various stages, the reactant [T(G)PPCoII], the transition-state, and the product [T(G)(PPCoNO)-N-II], was estimated to show that the cobalt atom carries relative effective positive charges of 2.000 in the reactant [T(G)PPCoII], 2.350 in the transition state, and 2.503 in the product [T(G)(PPCoNO)-N-II], which indicates that the concerted NO transfer from Ph3CSNO to T(G)PPCoII with the release of the Ph3CS center dot radical was actually performed by the initial negative charge (-0.350) transfer from T(G)PPCoII to Ph3CSNO to form the transition state and was followed by homolytic S-NO bond dissociation of Ph3CSNO with a further negative charge (-0.153) transfer from T(G)PPCoII to the NO group to form the final product T(G)(PPCoNO)-N-II. It is evident that these important thermodynamic and kinetic results would be helpful in understanding the nature of the interaction between RSNO and metal porphyrins in both chemical and biochemical systems.
