摘要：
Two novel blue emitting adducts of 2-(2-hydroxyphenyl)-benzotriazole and benzo[de]isoquinoline-1,3-dione, have been synthesized for the first time by combination of benzotriazole UV-absorber and 1,8-naphthalimide fluorescent unit in one molecule. The new compounds have shown very good photostabilizing efficiency, indicating a high potential for simultaneous brightening and stabilization of polymers. The chemical bonding of the synthesized monomers in the polymer chain was confirmed spectrophotometrically. The influence of these additives on the photostability of the co-polymers was studied. The participation of combined molecules in the polymerisation did not significantly affect the co-polymer molecular weight. (c) 2004 Elsevier Ltd. All rights reserved.
