We report the synthesis of tripodal receptors with monopyrrolo-tetrathiafulvalene arms 1a,b, based on 1,3,5-substituted 2,4,6-triethylbenzene scaffold. The three converging pyrrolotetrathiafulvalene groups form an electron rich cone-shaped binding site. Molecular hosts 1a,b are capable of binding neutral electron deficient guests in solution, as well as positively charged pyridinium species in the
我们报道了基于1,3,5-取代的2,4,6-三乙苯支架的单吡咯并四硫富瓦烯臂1a,b的三脚架受体的合成。三个会聚的吡咯并四硫富瓦烯基形成富电子的锥形结合位点。分子主体1a,b能够结合溶液中的中性电子不足的来宾以及气相中带正电的吡啶鎓类物质。
