Abstract

A phenyl-substituted diazaperylenediium dication (DAP) was synthesized that shows concentration-dependent aggregation in water. The host-guest complexation of DAP was studied with the macrocyclic host cucurbit[]uril ( = 7, 8) in water. With CB[7], it forms a 1:2 complex by placing two aryl substituents inside the CB[7]; whereas, with CB[8], a supramolecular polymer is formed. The resulting complex and supramolecular polymer have been characterized by ITC (isothermal titration calorimetry), ESI-MS (electrospray ionization mass spectrometry), H NMR (proton nuclear magnetic resonance), 2D NOESY (two-dimensional nuclear Overhauser enhancement spectroscopy), and DOSY (diffusion-ordered spectroscopy) spectra.

摘要

合成了一种苯基取代的二氮杂苝二价阳离子（DAP），其在水中表现出浓度依赖性聚集。在水中研究了DAP与大环主体葫芦脲（ = 7, 8）的主客体络合作用。与CB[7]反应时，通过将两个芳基取代基置于CB[7]内部形成1:2络合物；而与CB[8]反应时，则形成超分子聚合物。所得络合物和超分子聚合物已通过等温滴定量热法（ITC）、电喷雾电离质谱（ESI-MS）、核磁共振氢谱（H NMR）、二维核Overhauser增强光谱（2D NOESY）和扩散排序光谱（DOSY）进行了表征。
