Hydrogels are a class of hydrophilic polymers that have been widely applied in numerous fields, most of which are related to bioengineering such as tissue scaffolds, biosensing and antibacterial activity. Especially, polyacrylamide (PAAm) hydrogels, due to their superior stability, non-toxicity and viscoelasticity, have been extensively studied over the last two decades in different bio-related applications. Coordination polymers (CPs) including metal-organic frameworks (MOFs), due to tunability of the organic linkers and metal ions, and their robustness, have been incorporated with hydrogels in order to improve the physical/chemical properties of the final composite. Herein, we report for the first time, the use of a photoactive Cu(I) coordination polymer, as Norrish type II photoinitiator, for the visible light-induced in situ fabrication of a clickable and highly-crosslinked Cu(I)CP-PAAm hydrogel composite using water as the solvent. Due to the high stability of the Cu(I)CP in water, that was demonstrated by powder X-ray studies, the release of copper ions was observed to occur after more than two days. Another advantage of the developed synthetic method, is the possibility to readily post-modify the hydrogel-composite by employing an azide-functionalized polymer through internal copper-catalyzed azide-alkyne click reaction.
