摘要

不饱和体系的精确设计仍然是一个重要因素，它不仅决定了基于特定空间取向形成的产物的质量，而且还确定了可用的  电子密度，以便通过氧化还原变化进行合成后调节。三种严格定义的试剂显示出不同程度的灵活性，同时也引入了两种反应端的相互取向（平行和钝角），这决定了通过分子内或分子间反应所形成的产物的质量。单环和双环系统的氧化还原活化转化会产生不同的强π-共轭二价氧化态（2 个电子过程）或阳离子-自由基氧化态（1 个电子过程），这分别源于单体和二聚体所记录的骨架动态的不同。

Folding of a Dynamic Macrocyclic System to Stabilize its Cation Radical State

A precise design of unsaturated systems remains an important factor that determines the quality of formed products based on a specific spatial orientation, but also defining the available -electron density open for postsynthetic modulation via a redox change. Three strictly defined reagents showing a different degree of flexibility, but also introducing two mutual orientations of reacting ends (parallel and obtuse) determine the quality of formed products obtained via an intramolecular or an intermolecular reaction. The redox activated transformation of mono- and double-looped systems results in a dissimilar oxidation state of a strongly pi-conjugated dication (2 electron process) or a cation-radical (1 electron process) derived from the difference in dynamic of the skeleton documented for monomer and dimer, respectively.
