Molecular recognition to preorganize noncovalently polymerizable supramolecular complexes is a characteristic process of natural supramolecular polymers, and such recognition processes allow for dynamic self-alteration, yielding complex polymer systems with extraordinarily high efficiency in their targeted function. We herein show an example of such molecular recognition-controlled kinetic assembly/disassembly processes within artificial supramolecular polymer systems using six-membered hydrogen-bonded supramolecular complexes (rosettes). Electron-rich and poor monomers are prepared that kinetically coassemble through a temperature-controlled protocol into amorphous coaggregates comprising a diverse mixture of rosettes. Over days, the electrostatic interaction between two monomers induces an integrative self-sorting of rosettes. While the electron-rich monomer inherently forms toroidal homopolymers, the additional electrostatic interaction that can also guide rosette association allows helicoidal growth of supramolecular copolymers that are comprised of an alternating array of two monomers. Upon heating, the helicoidal copolymers undergo a catastrophic transition into amorphous coaggregates via entropy-driven randomization of the monomers in the rosette.

使非共价聚合的超分子复合物预先组织化的分子识别是天然超分子聚合物的特征过程，并且这种识别过程允许动态自改变，从而产生在其目标功能方面极其高效的复合聚合物系统。我们在本文中显示了使用六元氢键合超分子复合物（玫瑰红）在人工超分子聚合物系统中进行此类分子识别控制的动力学组装/拆卸过程的示例。制备了富电子和不良电子的单体，它们通过温度控制方案在动力学上共组装成非晶形的聚集体，该聚集体包括各种花环混合物。经过几天的时间，两种单体之间的静电相互作用诱导了莲座丛的整体自分选。尽管富电子单体固有地形成环形均聚物，但也可以引导玫瑰花结缔合的额外静电相互作用允许超分子共聚物的螺旋状生长，该超分子共聚物由两种单体的交替排列组成。加热后，螺旋体通过玫瑰花结中单体的熵驱动随机化经历灾难性转变为无定形共聚体。
