Synthesis Of Organic Gelator With M-benzoyldiamide And Properties Of Gelatin And Recognition

In recent years,supramolecular chemistry has become attracted much attention in the fron -t topic research.As differ from molecular chemistry,supramolecular chemistry aims to investi -gate aggregation mode of moleculars on the base of the non-covalent bonding interactions (such as H-bonding, van der Walls,Ï€-Ï€stacking and so on).In the design of so many molecul -ar congeries with multifarious structures and functions,supramolecular chemistry displays splendid prospects in the application of material,medicine,energy sources and environment.The main purpose of this thesis is designing and synthesizing organic compouds with m- benzoyldiamide(1i,2i):(1)A dimethyl 5-hydroxyisophthalate derivative is designed and synthe -sized with the incorporation of three methoxyl chains,2-aminopyridine and 4-(2-aminoaethy -l)-benzophenone;(2)Another dimethyl 5-hydroxyisophthalate derivative which contains three long chains,2-aminopyridine and 4-(2-aminoaethyl)-benzophenone is also synthesized. In add -ition,the structures of the synthesized compouds are comfirmed by 1HNMR,MS and element analysis.We have investigated that the possibility and ability of 1i and 2i to form organogel singly ;And the driving force for the formation of the gel system is analysed.The gelling ability of the two component gel system by the incorporation of substance A or B is also studied.The recognition property of 2i to fluorescent compound(C,D) is discussed.The fluorescen -ce intensity of C and D is influenced by 2i,the association constant and mode are aslo indicated.
