A related series of bisamides have been evaluated for rational correlation between anion complexation and organocatalysis: remarkable enhancement of hydrogen bonding to anions was observed along with significant increases in catalytic activity in the Baylis–Hillman reaction. In addition, X-ray crystallography showed a large degree of pre-organisation was observed in one receptor by incorporation of

Anion-templated pseudorotaxane formation is effectively controlled by macrocycles that expand and contract in response to a light stimulus. Upon light-induced threading and dethreading, the axle component can dynamically relocate between the macrocycle and a secondary isophthalamide host. This work is a stepping stone towards signal processing in multicomponent supramolecular systems.

Synthetic anion transmembranetransporters are adding new aspirations for treating channelopathies by replacing defective ion channels. The availability of such suitable candidates is still infrequent due to the associated toxicity. Here, we report 3-(1H-1,2,3-triazol-1-yl)benzamides as transmembrane anion carriers, nontoxic to cells. The selective and electrogenic chloride transport activity was established
合成阴离子跨膜转运蛋白通过替换有缺陷的离子通道为治疗通道病增添了新的希望。由于相关的毒性,此类合适候选物的可用性仍然很少。在这里,我们报告了 3-(1 H -1,2,3-triazol-1-yl)benzamides 作为跨膜阴离子载体,对细胞无毒。通过基于荧光和离子选择性电极的测定确定选择性和电生成氯化物转运活性。MQAE 测定证实无毒化合物将氯化物吸收到细胞中。
