A quantitative model that describes the assembly of diketopyrrolopyrrole-based donors and a perylenediimide acceptor into chiral superstructures, as a result of both hydrogen bonding and π•••π stacking. This model provides thermodynamic parameters (ΔH° and ΔS°) for all noncovalent interactions involved in the assembly and explains the subtle supramolecular cues that convert disordered aggregates into well-defined helical assemblies.
一个定量模型描述了基于二酮吡咯吡咯烯的供体和苝二酰亚胺受体组装成手性超结构的过程,这是由于氢键和π•••π堆积的结果。该模型提供了所有非共价相互作用涉及的热力学参数(ΔH°和ΔS°),并解释了微妙的超分子信号,将无序聚集体转化为明确定义的螺旋组装体。
