Novel Fluorescence Probes Based on 2,6-Donor−Acceptor-Substituted Anthracene Derivatives
摘要:
The fluorescence properties of selected derivatives of 6-methoxyanthracene-2-carboxylic acid were studied. The corresponding ester and oxazoline derivatives exhibit a moderate solvatochromism, which is caused by the donor-acceptor 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 switchable acceptor strength.
