Abstract

A novel [c2] daisy chain was successfully constructed by the hermaphroditic monomer of dibenzo[24]-crown-8 (DB24C8) derivative bearing secondary ammonium salt (1) from the analysis of the solution-phase behavior of parent monomers and single-crystal X-ray analysis. ¹H NMR spectroscopy was employed to show that the crown ether moiety and the secondary ammonium salt unit underwent acid–base and alkali metal cation dependent switches. The complexation behavior of this hermaphroditic monomer in the solution was further demonstrated to exhibit the controlled photophysical behavior as a reversible luminescent switch in the presence of acids or bases. Solid morphology was determined by SEM.

含二苯并-24-冠-8铵盐基团的化学控制自组装行为

通过对母体单体的固相行为分析和单晶x射线分析，以二苯并[24]-冠-8 (DB24C8)衍生物(1)为载体，成功构建了新的[c2]菊花链。核磁共振氢谱分析表明，冠醚部分和仲铵盐单元发生了酸碱和碱金属阳离子依赖的转换。这种两性单体在溶液中的络合行为进一步证明了在酸或碱存在下作为可逆发光开关表现出受控的光物理行为。用扫描电镜观察固体形貌。

期刊介绍： The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites. The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
