    The supramolecular polymeric aggregation behaviour of these ILs has been studied through high-resolution electron spray ionization mass spectrometry (HR-ESI-MS). Furthermore, these ILs were applied as catalyst/phase transfer catalyst in the synthesis of tetrahydrobenzo[b]pyran and its derivatives. These reactions were conducted in aqueous medium under ultrasound assistance. The results suggested that

    RTILs exhibit supramolecular self-assembled polymeric aggregation due to noncovalent interactions. The influence of the aggregation behaviour of RTILs on catalytic activity is evident but still poorly understood. The present work focuses on establishing a relationship between the role of supramolecular self-assembly of RTILs on catalysis in organic reactions. Herein, we report four unreported, air
    由于非共价相互作用,RTIL表现出超分子自组装聚合物聚集。RTILs的聚集行为对催化活性的影响是显而易见的,但仍然知之甚少。目前的工作集中在建立RTILs的超分子自组装对有机反应催化的作用之间的关系。在此,我们报告了四种未报告的,空气和水稳定,无卤化物,C 2对称的第三代疏水性咪唑基室温离子液体(RTIL 1-4),它们的合成和催化4H-的合成的作用-色烯衍生物(四氢苯并[ b] pyran)和Knoevenagel缩合。RTIL显示出前所未有的溶解度/混溶性。RTIL显示2-氨基苯甲酸1,3-二己咪唑鎓[hhim] [OAB](RTIL-3)在产率和反应时间方面表现更好。利用ESIMS探索了超分子聚合聚集体,同时通过记录RTIL在无水乙醇中的电导率来计算临界聚集体浓度(CAC)。我们还使用流变学实验来探索控制RTILs液相中聚集体发生的力。
