A new cholesterol organogelator 1 was synthesized, which was confirmed as an effective gelator for various organic solvents and could self-assemble into network fibers in some organic solvents. Moreover, gelator 1 could act as templates for the synthesis of various CuS nanofibers with different helical pitches. For example, when H(2)S was used as the sulfur source, straight and bending helical CuS nanofibers with a pitch of 100-200 nm could be fabricated in butyl acetate and benzene-butanol gel systems, respectively, while bending CuS nanofibers with a similar helical pitch (ca. 50 nm) could be obtained when thioacetamide was used as the sulfur source in both gel systems. It was first found that the morphologies of inorganic nanofibers could be controlled by the binding sites between the inorganic precursor and the organogel.
合成了一种新型胆固醇有机凝胶剂1，证实其对多种有机溶剂是有效的凝胶剂，并且在某些有机溶剂中能自组装成网络纤维。此外，凝胶剂1可作为模板用于合成具有不同螺旋间距的各种硫化铜纳米纤维。例如，当使用H₂S作为硫源时，分别在乙酸丁酯和苯 - 丁醇凝胶体系中可制备出螺距为100 - 200 nm的直的和弯曲的螺旋状硫化铜纳米纤维，而当在两个凝胶体系中都使用硫代乙酰胺作为硫源时，可获得具有相似螺旋间距（约50 nm）的弯曲硫化铜纳米纤维。首次发现无机纳米纤维的形态可通过无机前驱体与有机凝胶之间的结合位点来控制。
