A fluorescent and colorimetric sensor for Al3+ based on a dibenzo-18-crown-6 derivative
摘要:
A new receptor based on a dibenzo-18-crown-6 derivative is successfully synthesized and characterized. This receptor reveals selective recognition toward Al3+ ion, along with colorimetric and fluorometric dual-signaling responses based on internal. charge transfer (ICT). Also, it can serve as a highly selective chemodosimeter for Al3+ with naked-eye detection. (c) 2013 Elsevier B.V. All rights reserved.
