Hierarchical helicates based on ketone‐substituted titanium(IV)triscatecholates show different monomer‐dimer behavior depending on different solvents. The dimerization constants of a whole series of differently alkyl‐substituted complexes is analyzed to show that the solvent has a very strong influence on the dimerization. Hereby, effects like solvophobicity/philicity, sterics, electronics of the substituents and weak side‐chain—side‐chain interactions seem to act in concert.

酮取代三邻苯二酚钛(IV)配合物单体-二聚体平衡的溶剂依赖性

基于酮取代三邻苯二酚钛(IV)的多级螺旋化合物根据不同的溶剂表现出不同的单体-二聚体行为。分析了一系列不同烷基取代的配合物的二聚常数，表明溶剂对二聚有很强的影响。因此，诸如疏溶剂性/亲和性、空间立体、取代基的电子性和弱侧链-侧链相互作用等效应似乎协同作用。
