两亲性树状大分子的计算机组装

Computer Assembly of Cluster-Forming Amphiphilic Dendrimers

Bianca M. Mladek, Gerhard Kahl, Christos N. Likos

摘要:

最近的理论研究预测了一种新的软物质粒子的成簇机制,这种粒子通过某种纯粹的排斥性、有界势相互作用。在足够高的密度下,在流体中形成重叠颗粒的簇,其在进一步压缩时结晶成具有与密度无关的晶格常数的立方晶格。在这项工作中,我们表明,两亲性树枝状聚合物是合适的胶体实验实现这一现象。因此,我们为合成这样的大分子铺平了道路,这些大分子构成了一类具有不寻常特性的新型材料的基础。

英文摘要:

Recent theoretical studies have predicted a new clustering mechanism for soft matter particles that interact via a certain kind of purely repulsive, bounded potentials. At sufficiently high densities, clusters of overlapping particles are formed in the fluid, which upon further compression crystallize into cubic lattices with density-independent lattice constants. In this work we show that amphiphilic dendrimers are suitable colloids for the experimental realization of this phenomenon. Thereby, we pave the way for the synthesis of such macromolecules, which form the basis for a novel class of materials with unusual properties.
