摘要：
A new macropolycycle, 2,13-dimethyl-1,5,12,16-tetraazapentacyclo[14.6.2.2(5.12).0(6.11).0(17.22)]hexacosane (L(3)), has been prepared by the reaction of 3,14-dimethyl-2,6,13,17-tetraazatricyclo[16.4.0.0(7.12)]docosane (L(1)) with 1-bromo-2-chloroethane. The macropolycycle readily reacts with anhydrous copper(II) ion to yield [CuL(3)](2+) in dry methanol but does not with nickel(II) ion, showing a high copper(II) ion selectivity. Crystal structure of [CuL(3)](ClO(4))(2) shows that the complex has a distorted square-planar coordination polyhedron with a trans-IV type N-conformation. The Cu-N distances [1.989(3) and 2.015(3) angstrom] of [CuL(3)](ClO(4))(2) are distinctly shorter than those of [CuL(1)](ClO(4))(2) and other related macrocyclic copper(II) complexes. The d-d transition band for [CuL(3)](ClO(4))(2) is observed at 447 nm, which is ca. 40 nm shorter than that for [CuL(1)](ClO(4))(2). (C) 2009 Elsevier B. V. All rights reserved.
