Polymersomes, hollow spherical nano-to-microscale polymer assemblies, have increasingly become important constructs in the development of biomimetic materials that expand the library of functional and robust analogs to lipid-based vesicles. As compared to liposomes, polymersomes possess superior physical properties and the nearly unlimited potential for synthetic fine-tuning. Herein we improve on the physical properties of these polymer vesicles by introducing platinum-based metal–ligand cross-links into the hydrophobic core, which gave the vesicles demonstrated resistance to destabilization by surfactants over un-cross-linked polymersomes. The formation of cross-links was capable of being selectively reversed by the addition of phosphines. In addition, the Pt(0) cross-links retained their catalytic activity for the hydrosilylation of alkenes.

合适的交联：具有催化活性的金属-配体键增强的聚合物囊泡

中空球形纳米到微米级聚合物组装体Polymersomes在仿生材料开发中已日益成为重要的构建体，仿生材料将功能强大的类似物库扩展到基于脂质的囊泡。与脂质体相比，聚合体具有优越的物理性能，并且具有合成微调的几乎无限的潜力。在这里，我们通过将铂基金属-配体交联引入疏水核中来改善这些聚合物囊泡的物理性能，这使囊泡比未交联的聚合物囊泡具有更强的抗表面活性剂稳定性的能力。交联的形成能够通过添加膦而选择性地逆转。此外，Pt（0）交联保留了其烯烃氢化硅烷化的催化活性。
