Fluorescent cryogels based on copolymers of N,N-dimethylacrylamide and allyl derivatives of 1,8-naphthalimide

New polymer cryogels based on N , N -dimethylacrylamide and allyl derivatives of 1,8-naphthalimide have been synthesized. They have intense fluorescence in the visible region of the spectrum. The influence of synthesis conditions on the properties of the resulting products has been studied. The maximum yield of the gel fraction and the minimum degree of swelling of the crosslinked polymer are observed during the lowtemperature (–20°C) synthesis of cryogels. Their fluorescence depends on the monomer content reaching the maximum value at concentrations of N , N -dimethylacrylamide and a fluorophore-containing monomer of 1.0 and 1.0 × 10 –3 mol/L, respectively.
