Stimuli‐Responsive Supramolecular Polymers of Mono‐ and Bis‐triazolylphenylazoaniline‐Functionalized Copillar[5]Arenes: With Distinctive Binding Modes

Chemistry – An Asian Journal, EarlyView.
Mono‐ and bis‐functionalized copillar[5]arenes 1 and 2 form pH‐ and photo‐responsive supramolecular polymers. Protonation of 1 enhances polymerization (1‐H), differing from neutral 2, which forms a 1:1 complex with DMP5 via cavity binding. Polymerization and morphology are tunable by pH and light, as shown by NMR, UV–vis, and FE‐SEM analyses.

Design and Synthesis of Triazole‐Based p‐tert‐Butylcalix[4]Arene Conjugates and Evaluation of Their Antimicrobial, Antibiofilm, and Anti‐Quorum‐Sensing Activities

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Macrocyclic calix[n]arenes have many applications, with diverse structures that can easily be functionalized either on upper or lower rims, mostly to impart solubility and improve biological activities. In this study, triazole‐based p‐tert‐butylcalix[4]arene conjugates (AT10a and AT10b) and their p‐tert‐butylphenol analogs (AT10b and AT11b ...

Ligand synthesis catalyst and complex metal ion: multicomponent synthesis of 1,3-bis(4-phenyl-[1,2,3]triazol-1-yl)-propan-2-ol copper(i) complex and application in copper-catalyzed alkyne-azide cycloaddition [PDF]

, 2016
A new bistriazole copper complex was synthesized by direct treatment of an alkyne, an azide, and CuI as copper salt through in situ ligand formation under a multicomponent reaction process. This complex was analyzed by XPS, TGA, DSC, and SEM techniques
