                                    We have developed new chromophoric derivatives for the amino group: 4,5-dimethoxyphthalimide and 6,7-dimethoxy-2,3-naphthalimide, particularly suitable for CD applications. These highly fluorescent imides show very strong Cotton effects due to exciton coupling which are red-shifted with respect to the parent phthalimide and 2,3-naphthalimide chromophores. No significant Cotton effects other than those due to the transition with the electric dipole transition moment colinear with the Ct-axis of the chromophore were observed, (C) 1999 Elsevier Science Ltd.
