摘要：

The basic photophysical characteristics of two fluorophores: monomeric N,N-dimethylaminoethylene-N-allyl-1,8-naphthalimide and methylmethacry late based copolymer including NN-dimethylaminoethylene-N-allyl-1,8-naphthalin-tide are described both in the absence and presence of Fe2+, Ph2+, Zn2+ and Ni2+ cations. It is shown that both the fluorophores can be used as homogeneous photo-induced electron transfer fluorescent sensors exhibiting fluorescence enhancement induced by metal ions. The copolymer is more responsive to the Fe2+ cations than to other cations under study. (C) 2003 Elsevier Science B.V. All rights reserved.
