“协调驱动自组装”为我们提供了一种高效的方法，可以通过简单的构建块来制造形状和尺寸可控的3D金属镀层和2D金属循环。本文采用“配位驱动自组装”的方法，成功构建了一种新的离散型铂（II）两亲体（AOM），该两亲体包含亲水性三（环氧乙烷）链和疏水性卟啉单元。通过紫外可见光谱、动态光散射、透射电子显微镜、扫描电子显微镜、小角度x射线散射等表征方法，我们发现aom在室温下可以自组装成囊泡、开口弯曲的囊泡，并最终在水溶液中形成稳定的双层纳米管，在60℃左右形成柔性交联结构。相反，aom在正己烷中形成了宽度为微米、长度为毫米的刚性双层纳米片。我们希望这项研究将为制造可控软材料铺平道路。
“Coordination-driven self-assembly” offers us an efficient method to fabricate 3D metallacages and 2D metallacycles with controllable shape and size via simple building blocks. Herein, a new discrete platinum(II) amphiphile (AOM), which contains hydrophilic tris(ethylene oxide) chains and a hydrophobic porphyrin unit, was constructed successfully by using “coordination-driven self-assembly”. From various characterization methods, such as UV–vis spectroscopy, dynamic light scattering, transmission electron microscopy, scanning electron microscopy, and small-angle X-ray scattering, we found thatAOMcan self-assemble into vesicles, curved vesicles with open ends, and at last stable bilayer nanotubes in aqueous solution at room temperature and flexible cross-linked structures at about 60 °C. In contrast,AOMformed rigid bilayer nanosheets of micrometers in width and millimeters in length inn-hexane. We hope this investigation will pave the way for the fabrication of controllable soft materials.
