We introduce a molecular dynamics (MD) coarse-grained model for the description of tripod building blocks. This model has been used by us already for linear, V-shape, and tetratopic molecules. We wanted to further extend its possibilities to trifunctional molecules to prove its versatility. For the chosen systems we have also compared the MD results with Monte Carlo results on a triangular lattice. We have shown that the constraints present in the latter method can enforce the formation of completely different structures, not reproducible with off-lattice simulations. In addition to that, we have characterized the obtained structures regarding various parameters such as theoretical diffraction pattern and average association number.
我们引入了一种用于描述三脚架构建单元的分子动力学(MD)粗粒化模型。我们已经将该模型用于线性、V形和四官能团分子。我们希望进一步扩展其对三官能团分子的适用性,以证明其通用性。对于所选系统,我们还将MD结果与三角晶格上的蒙特卡罗结果进行了比较。我们已经表明,后一种方法中存在的约束可以强制形成完全不同的结构,这是无晶格模拟无法重现的。除此之外,我们还根据各种参数(如理论衍射图案和平均缔合数)对所得结构进行了表征。
