摘要：
A simple Schiff-base fluorescent receptor I was synthesized in an one step procedure. Receptor 1 displayed a selective colorimetric change (from light yellow to light green) and high ratiometric signals upon binding to Al3+ in EtOH solution. The association constant for 1-Al3+ in EtOH was determined as 2.08 x 10(6) M-2 and the detection limit for Al3+ was determined as 5.21 x 10(-7) M. The detection limit was sufficiently low to detect submicromolar concentration of the Al3+. (C) 2014 Elsevier B.V. All rights reserved.
