The morphology of surfaces critically influences their interaction with the surrounding phase. Herein, we report a modular approach for the synthesis of organic–inorganic raspberry-, strawberry-, and seedpod-like particles to template the porosity of superficially porous particles. Divinylbenzene (DVB) microspheres were employed as core particles, which were modified with polar and nonpolar polymer shells. Subsequently, silica nanoparticle templates were covalently tethered to said particles. Further grafting of polymer shells and subsequent template removal yielded superficially porous core–shell particles. In addition, we introduce a facile procedure for the synthesis of superficially porous particles without distinguishable core–shell morphology. Organic seedpod-like particles were prepared from DVB and silica templates, yielding superficially porous particles after template removal. The surface morphology of the templated particles was investigated via scanning electron microscopy (SEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM). X-ray photoelectron spectroscopy (XPS) was performed to prove the chemical modification of the particle surfaces.

缺少水果沙拉的两种葡萄：通过胶体纳米模板化的覆盆子，草莓和种子荚状有机微球

表面的形态严重影响了它们与周围相的相互作用。在这里，我们报告了一种模块化方法，用于合成有机-无机覆盆子，草莓和种荚状颗粒，以表面多孔颗粒的孔隙度为模板。二乙烯基苯（DVB）微球用作核心颗粒，并用极性和非极性聚合物壳改性。随后，将二氧化硅纳米颗粒模板共价拴系到所述颗粒。聚合物壳的进一步接枝和随后的模板去除产生了表面多孔的核-壳颗粒。此外，我们引入了一种简便的方法来合成表面多孔颗粒，而没有明显的核-壳形态。由DVB和硅胶模板制备了类似有机种的种子荚，去除模板后产生表面多孔的颗粒。通过扫描电子显微镜（SEM），透射电子显微镜（TEM）和原子力显微镜（AFM）研究了模板化颗粒的表面形态。进行X射线光电子能谱（XPS）来证明颗粒表面的化学改性。
