Procedure
8.2 g of sodium borohydride was added to a suspension of 4,4′-diethoxycarbonyl-4″-nonadecyl-2,2′:6′,2″-terpyridine (6.4 g, 10.0 mmol) in 200 mL of absolute ethanol. The mixture was refluxed for 3 h and cooled to room temperature, and then 200 mL of an ammonium chloride saturated water solution was added to decompose the excess borohydride. The ethanol was removed under vacuum and the precipitated solid was dissolved in a minimal amount of water. The resulting solution was extracted with ethyl acetate (5×200 mL) and dried over sodium sulfate, and the solvent was removed under vacuum. The desired solid was obtained in 79% yield and was used without further purification. Anal. C36H53N3O2: Calcd: C, 77.24; H, 9.54; N, 7.51. Found: C, 77.10; H, 9.47; N, 7.49. MS (ESIMS): m/z: 559.4.
