A new blue emitting 2‐allyl‐6‐(2‐dimethylaminoethyloxy)‐benzo[ de ]isoquinoline‐1,3‐dione, bearing an allylic group has been designed and synthesized. Bulk radical copolymerization has been carried out in order to prepare a fluorescent copolymer, based on styrene. The main photophysical characteristics of the monomeric and polymeric fluorophores have been investigated both in the absence and presence of metal cations and protons. It has been found that the monomeric naphthalimide can be used as a sensor for protons and Zn 2+ , Ni 2+ , Ce 3+ , Cu 2+ , Co 2+ , Ag + cations. The polymeric fluorophore has been shown to be a selective chemosensor for Cu 2+ cations. Copyright © 2006 John Wiley & Sons, Ltd.
