We report on the direct formation of 1D nanostructures of two coordination polymers based on copper(i)-iodine double chains decorated with ethyl isonicotinate or 2-amino-5-nitropyridine as terminal ligands. The use of different reaction conditions, e.g. energy of the formation process, solvents, and/or concentration of reactants, has allowed the control of the size of the fibres and ribbons directly formed in this process going from micron- to submicron- up to nano-size. We show experiments that direct the formation of materials kinetically versus thermodynamically controlled, adjusting simple experimental parameters. Finally, a morphological study on the Cu(i)-iodine bearing 2-amino-5-nitropyridine nanofibres has confirmed their reversible molecular recognition ability towards acetic acid vapours.
我们报道了两种基于铜(I)-碘双链并以异烟酸乙酯或2-氨基-5-硝基吡啶作为末端配体修饰的配位聚合物的一维纳米结构的直接形成。通过使用不同的反应条件,例如形成过程的能量、溶剂和/或反应物浓度,能够控制在此过程中直接形成的纤维和带的尺寸,范围从微米级到亚微米级直至纳米级。我们展示了通过调整简单的实验参数,动力学控制与热力学控制材料形成的实验。最后,对含2-氨基-5-硝基吡啶的铜(I)-碘纳米纤维的形态学研究证实了它们对乙酸蒸汽具有可逆的分子识别能力。
