A new type of building block with two coordinatively unsaturated
palladium centres has been described that self-assembles in nitromethane
solution and disassembles when acetonitrile is added. The resulting
hyperbranched, organopalladium spheres have a remarkably narrow size
distribution as was evidenced by light-scattering, AFM and TEM
measurements. Variation of the structure of the building blocks showed the
possibility to vary the size of the self-assembled spheres between 100 and
400 nm.
一种新型的建筑块已被描述,其具有两个配位不饱和的钯中心,并在硝基甲烷溶液中自组装,当加入乙腈时则解体。生成的超支化有机钯 spheres 具有显著狭窄的尺寸分布,这通过光散射、原子力显微镜(AFM)和透射电子显微镜(TEM)测量得到了证实。建筑块结构的变化显示了自组装 spheres 的尺寸可以在100至400纳米之间变化的可能性。
