摘要

A cyclen (= 1, 4, 7, 10-tetraazacyclododecane) doubly functionalized with three carbamoylmethyl groups and one dansylaminoethyl (dansyl= 2-(5-(dimethylamino)-1- naphthalenesulfonyl) group (L2= 1-(2-(5-(dimethylamino)-1-naphthalenesulfonylamido) ethyl)-4, 7, 10-tris (carbamoylmethyl)-cyclen) was synthesized and characterized. Potentiometrtic pH titration and UV spectrophotometric titration of L2 served to determine ...
