| Recently, micelle, especially metallomicelle made of metal complex and micelle as model systems for artificial hydrolytic enzyme are the very active research field. This dissertation focuses on the following two aspects: the effects of several kinds of additives on micellization of surfactants and on micellar catalysis; the hydrolysis of carboxylic acid esters and phosphate esters catalyzed by metal complex and metallomicelle. The results obtained may provide theoretical basis and significative information for finding out the hydrolytic mechanism of enzymes and for designing highly efficient artificial enzyme model systems. The effects of both cyclodextrins on micellization of SDS, CTAB, Brij35 and several types of amine on micellization of CTAB and SDS have been systematically investigated, respectively. On the basis of the results, a series of empirical formulae depicting the relationships between the concentration of additives and critical micelle concentration (cmc) values of surfactants have been obtained, and how the additives influence the micellization of surfactant were also discussed in detail. The hydrolysis of carboxylic acid esters (p-nitrophenyl picolinate (PNPP) and p-nitrophenyl acetate (PNPA)) catalyzed by amphiphilic α-, β-, and γ-cyclodextrin was studied kinetically. The experimental kinetic data were treated with phase separation model for micellar catalysis, which was proved reasonable in the above systems. The results indicated that the binding constants between cyclodextrin and substrate and the rate constants for the reactions followed the completely opposite sequence, which was ascribed to the different cavity sizes of cyclodextrins.In order to mimic the natural carboxylic acid esterase, the hydrolysis of PNPP catalyzed by metallomicelles made of Zn(II), Cu(II) and Co(II) complexes of imidazole derivatives and three kinds of surfactants(CTAB, Brij35 and LSS)have been investigated kinetically。The results suggested that Zn(II)complex exhibit a great catalytic activity in micellar solutions with higher pH value,which may be attributed to the different ionization states of the corresponding complexes in micellar media with different pH values and the different nucleophilic ability of active species in different complexes. Two oximato copper (II) complexes were synthesized and characterized. And hydrolysis of carboxyl acid esters (PNPP and PNPA), catalyzed by these two complexes was investigated in different micellar systems. The results obtained indicated that these two complexes bearing oxime groups exhibit highly catalytic activity on the hydrolysis of both PNPP and PNPA. It also suggested that both complexes accelerate the hydrolytic cleavage of PNPP and PNPA in cationic CTAB micellar solution faster than that in nonionic Brij35 micellar solution, which may be due to the different coordinating ability of substrates to complexes and the electrostatic interaction between micelle and complexes or substrates. In order to shed light on the crucial role of lanthanide ion played in the catalytic hydrolysis of phosphate esters, the hydrolysis of bis(p-nitrophenyl phosphate) (BNPP) and p-nitrophenyl phosphate (NPP) catalyzed by mononuclear La(III) complex and hetero-dinulcear Cu(II)La(III) complex was investigated in Φ=0.50 dimethyl sulfoxide(DMSO)-water mixing solvent. The results indicated that both BNPP and NPP hydrolyses were greatly promoted by these two complexes; the hetero-dinuclear Cu(II)La(III) complex exhibited relatively higher catalytic activity on NPP hydrolysis, while the hydrolysis of BNPP was slightly more efficient in the presence of the mononuclear La(III) complex than that in the presence of Cu(II)La(III) complex, and this case was discussed by the different space requirements for NPP and BNPP hydrolyses.As the development of surfactant chemistry, researchers have paid much more attention to Gemini surfactant owing to its unique properties. The hydrolysis of PNPP and PNPA mediated by cationic Gemini dimethylene-1,2-bis (cetyltrimethylammonium b...
