Given the recent report of a novel pyrazole receptor exhibiting a high selectivity for NH4+ over K+, it would be interesting to investigate the origin of this selectivity and affinity so that better receptors could be designed. On the basis of extensive theor. studies, we conclude that the origin arises from a subtle interplay of charged H-bonds and cation-π interactions. The approach employed herein would be very useful in the rational design of novel functional mol. systems. This study involved multiple reactions and reactants, such as 1,1′,1”-((2,4,6-Trimethylbenzene-1,3,5-triyl)tris(methylene))tris(1H-pyrazole) (cas: 172606-26-7Related Products of 172606-26-7).
1,1′,1”-((2,4,6-Trimethylbenzene-1,3,5-triyl)tris(methylene))tris(1H-pyrazole) (cas: 172606-26-7) belongs to pyrazole derivatives. The 1H-pyrazole provides an excellent means by which to provide the requisite hydrogen bond acceptor–donor motifs, whether as a monocyclic ring or as a fused indazole ring. Pyrazoles can be selectively lithiated at different carbons and subsequently react with electrophiles depending on the substitution patterns.Related Products of 172606-26-7
