To a mixture of Cu(NO3)22.5H2O (0.504 g, 2.17 mmol) in MeOH(15.0 mL), was added tris[2-(dimethylamino)ethyl]amine (L4)(0.500 g, 2.17 mmol) and stirred at RT. The blue solution was evaporatedunder reduced pressure to afford a yellow solid. The solidwas dissolved again in MeOH and diffused with diethyl ether. Suitableblue block-shaped crystals were obtained in 2 days. Yield(0.921 g, 98%).

To a solution of tris(2-dimethylaminoethyl)amine (0.326 g, 1.41 mmol) in acetonitrile (4 mL) was added 1-bromooctadecane (1.41g, 4.23 mmol). The resulting mixture was heated at reflux with stirring for 23 hours, during which time a white solid was observed. After cooling, and the addition of a cold hexanes/acetonemixture (15 mL, 1:1), to the reaction flask, the precipitate was filtered with a Buchner funnel, and rinsed with a cold hexanes/acetone mixture (20 mL, 1:1), resulting in T-18,18,18 (1.48 g, 85%) as a white powder; mp=227-259 C; ?H NMR (300 JVII-Tz, CDC13) oe 4.13-4.02 (m, 6H), 3.65-3.58 (m, 6H), 3.46-3.38 (m, 6H), 3.35 (s, 18H), 1.78-1.66 (m, 6H), 1.41-1.37 (m, 90H), 0.89-0.82 (m, 9H); high resolutionmass spectrum (ESI) in/z 330.0376 ([Mj3 calculated for [C66H,4,N4j3: 330.0380). ?H spectmm of compound T-18,18,18 can be found in Figure 55.
