General description

Azidobenzene is an aromatic azide generally used in copper(I)-catalyzed azide-alkyne cycloaddition reactions.
Azidobenzene solution can undergo click reaction with alkyne-functionalized oligomers to form O-ester-functionalized o-phenylenes, a group of aromatic foldamers with a good folding tendency in most solvents.

Application

Phenylazide in greener solvent, 2-methyltetrahydrofuran (2-MeTHF).

N-(3-trimethoxysilylpropyl)-4-azido-2,3,5,6-tetrafluorobenzamide (PFPA-silane) was used as a photoactive cross-linker to immobilize antibacterial furanone molecules on silicon oxide surfaces. This immobilization strategy is useful, especially for substrates and molecules that lack reactive functional groups. To this end, cleaned wafers were initially incubated
