Cage-like structures based on constrained cyclic arylopeptoids

Abstract

Selective access to cupola-like bis-triazolium architectures thanks to copper(i) N-heterocyclic carbene led to well-structured cage with potential for oxoanion recognition.

A pyrene–calix[4]triazolium conjugate for fluorescence recognition of hydrogen sulfate

“…To the best of our knowledge, 1,2,3-triazolium has never been introduced into an HSO 4 − selective receptor. 17 In addition, this is the first report of a macrocycle-based PET-active fluorescent chemosensor that selectively recognizes HSO 4 − .…”
