Stability and stimuli-responsiveness are important parameters for dynamic supramolecular polymers. Herein we have found that, as compared to cyclic alkanes, linear alkanes facilitate to enhancement of solvo-, thermo-stability and photo-resistance for platinum(II) acetylide-based one-dimensional supramolecular polymers. It is primarily ascribed to low steric hindrance for linear alkane solvents, which tend to intercalate into the gap of the peripheral alkyl chains and thereby display higher Gibbs free energy for supramolecular polymerization processes. In addition, supramolecular polymers exhibit high thermo-stability by incorporating higher-order acenes to platinum(II) acetylide core unit, because of their stronger π-π stacking strength. Accordingly, the current study highlights the importance of structure and solvent parameters for the rational design of platinum(II) acetylide-based supramolecular polymers.

稳定性和刺激响应性是动态超分子聚合物的重要参数。在本文中，我们发现，与环状烷烃相比，线性烷烃有助于提高基于铂（II）乙炔基的一维超分子聚合物的溶剂稳定性，热稳定性和光阻性。这主要归因于直链烷烃溶剂的低位阻，其倾向于插入到外围烷基链的间隙中，因此对于超分子聚合过程显示出更高的吉布斯自由能。另外，由于超分子聚合物具有更强的π-π堆积强度，因此通过将更高级的并苯并入乙炔铂（II）核心单元而显示出高的热稳定性。因此，
