Abstract
The fluorescence properties of selected derivatives of 6-methoxyanthracene- 2-carboxylic acid were studied. The corresponding ester and oxazoline deriv atives exhibit a moderate solvatochromism, which is caused by the donor-acc eptor interplay, The fluorescence band shift and intensity of oxazoline If may be reversibly modulated by protonation or complexation with silver ions ; thus, the oxazoline heterocycle serves as a useful substituent with switc hable acceptor strength.
