Radial Control of Recognition and Redox Processes with Multivalent Nanoparticle Hosts was written by Boal, Andrew K.;Rotello, Vincent M.. And the article was included in Journal of the American Chemical Society in 2002.COA of Formula: C7H9N3O This article mentions the following:
Mixed monolayer protected gold clusters (MMPCs) featuring both hydrogen bonding and aromatic stacking mol. recognition functionalities have been used to create multivalent hosts for flavins. Multitopic binding of these hosts to flavin was shown to have a strong radial dependence: when the recognition site was brought closer to the MMPC surface, recognition was enhanced 闂?-fold due to increased preorganization. The effect of preorganization is reversed upon reduction of flavin, where the MMPC with longer side chains bind the flavin guest 闂?-fold stronger than the short chain counterpart due to unfavorable dipolar interactions between the electron-rich aromatic stacking units of the host and the anionic flavin guest. This fine-tuning of recognition and redox processes provides both a model for enzymic systems and a tool for the fabrication of devices. In the experiment, the researchers used many compounds, for example, N-(6-Aminopyridin-2-yl)acetamide (cas: 1075-62-3COA of Formula: C7H9N3O).
N-(6-Aminopyridin-2-yl)acetamide (cas: 1075-62-3) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of 闂?8.7 闂?10闂? cm3闁荤姾娅ｅΛ纭俵闂?.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ闁荤姾娅ｅΛ纭俵闂? in the liquid phase and 140.4 kJ闁荤姾娅ｅΛ纭俵闂? in the gas phase. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.COA of Formula: C7H9N3O
