Design and synthesis of polymerizable, yellow-green emitting 1,8-naphthalimides containing built-in s-triazine UV absorber and hindered amine light stabilizer fragments

Two novel yellow-green emitting polymerizable 1,8-naphthalimide fluorophores, containing an UV absorber and a hindered amine light stabilizer (HALS) component were synthesized by combination of 2-hydroxyphenyl-1,3-5-triazine, 2,2,6,6-tetramethylpiperidine and allylamine. The combination of the two structural units in one molecule did not result in intramolecular fluorescence quenching. The compounds were copolymerized with acrylonitrile to yield polyacrylonitriles of intense color and fluorescence, indicating that the novel compounds offer potential for the “one-step” chemical coloration and stabilization of polymers.
