General description
Acid functionalized cyclooctyne derivative. Cyclooctynes are useful in strain-promoted copper-free azide-alkyne click chemistry reactions. This azadibenzocyclooctyne will react with azide functionalized compounds or biomolecules without the need for a Cu(I) catalyst to result in a stable triazole linkage.
Application
Dibenzocyclooctyne-acid may be used for the surface modification of eight-arm poly(ethylene glycol), to make it susceptible to strain promoted alkyne-azide cycloaddition (SPAAC) with PEG-bis-azide leading to the formation of hydrogels. These hydrogels are useful for protein immobilization.

Strategies to encapsulate cells in cytocompatible three-dimensional hydrogels with tunable mechanical properties and degradability without harmful gelling conditions are highly desired for regenerative medicine applications. Here we reported a method for preparing poly(ethylene glycol)-co-polycarbonate hydrogels through copper-free, strain-promoted azide-alkyne cycloaddition
