“…Finally, isoniazid was used as a model drug to study the sustained release behavior of the drug‐loaded IPN hydrogels. To the best of our knowledge, there are many reports on amine‐anhydride reaction in organic solvents, [ 39–43 ] but the research on the reaction in water for forming IPN hydrogels is unexplored. Therefore, the study is meaningful due to its first combination of amine‐anhydride reaction and photopolymerization into the preparation of IPN hydrogel.…”

Herein, interpenetrating network (IPN) hydrogels were successfully prepared for the first time through integrating two cross‐linking reactions in water in one pot, including amine‐anhydride reaction and subsequent photopolymerization. First, the polymer containing anhydride groups was prepared via free radical copolymerization of maleic anhydride and acrylamide. Second, the as‐prepared polymer was dissolved in water with polyacrylamine hydrochloride, N‐isopropylacrylamide, polyethylene glycol dimethacrylate, 2‐acrylamido‐2‐methylpropanesulfonic acid, and photoinitiator to obtain a homogeneous transparent solution. Third, the mixed solution was put in water bath of 50°C for 1 h to obtain the first network via the amine‐anhydride click reaction. Afterward, the second network was formed by photopolymerization. Finally, the swelling and drug release behavior of the hydrogels were studied with isoniazid as a model drug. The results show the IPN hydrogel possesses pH and temperature sensitivity and their controlled‐release behavior can be tuned via adjusting pH and temperature. In view of the advantages of amine‐anhydride reaction and photopolymerization, the strategy described here is of significance for the preparation of IPN hydrogel.

The sequence-controlled in-chain functionalized polymers exhibit sequence defined functional units in chain and show more potential and specific applications for polymer materials. [15][16][17] Hence, how to synthesize in-chain functionalized polymers with controlled sequence distribution of functional units became an increasingly attractive subject, which is also regarded as a Holy Grail in polymer chemistry. [18,19] Furthermore, 1,1-diphenylethylene (DPE) derivatives displayed special characteristics in living anionic polymerization. Because of their remarkable steric hindrance, DPE derivatives only can be copolymerized rather than homopolymerized. In previous researches, the DPE derivatives have been applied to synthesize sequence-determined functionalized polymers. [13,[20][21][22][23] To expand the functionalized polymers for the developed potential applications, postfunctionalization becomes indispensable. Günay et al. [24] provided a systematic overview of several frequently used postpoly merization modification reactions, which represent a versatile platform for the preparation of diversely functionalized polymers from a single precursor. Some classic and efficient reactions, such as click chemistry and hydrosilylation, have demonstrated extraordinary vitality in the area of polymer chemistry. [25][26][27][28][29][30] However, for most postpolymerization modification reactions, a specific catalytic system is usually required, such as a metal catalyst or photochemical catalysis, which increases the cost and complicates the procedure. Moreover, even a trace amount of metallic residue from the catalyst may affect the properties of the product and create biological toxicity. Herein, a facile, metal-free, one-pot multicomponent reaction (MCR) may have important application value for postpolymerization modification. Tao and co-workers [31,32] called the Ugi four-component reaction (Ugi-4CR) a multicomponent click reaction because it has a number of significant features in common with a traditional click reaction, such as modularity, atom economy, and high efficiency. The reaction also has novel features due to its reactive nature, such as mild reaction condition, being catalyst-free, and efficiently inducing multifunctionality at one location, which are very significant for further polymeric functionalization.As reported, the general methods used to combine MCR and polymer science can be divided into two types: polycondensation via MCR and postpolymerization modification.
