摘 要：It is extremely dificult toachievearapid and effcient modifcationofnatural polysaccharides,due tothe intrinsicstrong hydrogen bonding networks and the slow mass transfer process during the reaction ***,we found a fascinating anion-tunnel transmission phenomenon in the imidazolium-based ionic liquids with carboxylate anions.A novel click esterification of natural polysaccharides thus was demonstrated undera catalyst-free condition within a very short reaction time of15min at *** a super-rapid and highly eficient modification strategy is available for various polysaccharides(clluoe,starchinulin,pululan,dextranand xylan),difrentesterifcatonreactions(acetication,propionation benzoylation,and cyclohexylformylation),and high concentrations,claiming a revolutionary potential in polysaccharide chemistry industries.
