Most colloids are isotropic particles that assemble in regular crystal structures in solution and on surfaces. The general aim of this bilateral Sino-German collaboration is to develop innovative methods to prepare colloidal molecules, i.e. well-defined 1D, 2D and 3D clusters of anisotropic "Janus" or "patchy" particles and to investigate the self-assembly of such colloidal molecules in solution and on surfaces. This proposal has three central objectives: 1) Generation of Janus particles functionalized with polymer brushes; 2) Preparation, assembly and manipulation of Janus particles in a magnetic field; 3) Preparation and self-assembly of microscale inverse opals with polymer brushes, which should give rise to self-assembled photonic structures.

大多数胶体是各向同性颗粒，在溶液中和表面上以规则的晶体结构聚集。这项中德双边合作的总体目标是开发创新的方法来制备胶体分子，即定义明确的一维、二维和三维各向异性“Janus”或“斑块”粒子簇，并研究此类胶体分子在溶液和表面上的自组装。这一提议有三个中心目标：1)用聚合物刷子产生功能化的Janus粒子；2)在磁场中制备、组装和操纵Janus粒子；3)用聚合物刷子制备和自组装微型反蛋白石，这将产生自组装的光子结构。
