摘要：

Two crowned Schiff base manganese(III) complexes (MnL2Cl, L = L-1, L-2) were used to catalyze the hydrolysis of bis(p-nitrophenyl)phosphate (BNPP) in Gemini surfactants [bis(hexadecyidimethylammonium)hexane bromide (abbreviation 16-6-16, 2Br(-))] solution. In comparison with the rate of BNPP spontaneous hydrolysis, a six orders of magnitude in rate enhancement was observed in (MnL2Cl)-Cl-1/16-6-16 and (MnL2Cl)-Cl-2/16-6-16 systems. Owing to the different structure, (MnL2Cl)-Cl-2 shows better activity than (MnL2Cl)-Cl-1. Especially, the effects of three different micelles, i.e., 16-6-16 micelles, CTAB (hexadecyltrimethylammonium bromide) micelles, LSS (n-lauroooylsarcosine sodium) micelles, on the hydrolysis of BNPP catalyzed by (MnL2Cl)-Cl-2 were evaluated at pH7.50. Experimental observations clearly demonstrate that Gemini 16-6-16 micelle is the best one for BNPP hydrolysis among three kinds of micellar media. (C) 2007 Elsevier B.V. All rights reserved.
