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).

Photoreactive phenylazide-end-capped liquid copolymers were prepared by ring-opening copolymerization of epsilon-caprolactone (CL) and trimethylene carbonate (TMC) at an equimolar monomer feed ratio in the presence of a polyol, namely, a low-molecular-weight alcohol (di-, tri-, and tetraol) or poly(ethylene glycol) (PEG)

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

Ultrafast photolysis (lambda(ex) = 308 nm) of phenyl azide in 100% formic acid produces a broadly absorbing transient within the instrument time resolution (300 fs), which is assigned to an excited state of the azide. The azide excited state fragments
