A Fluorescent Probe for Al<sup>3+</sup> Based on Calix[4]arene Containing Salicylaldehyde‐Derived Schiff Base
نویسندگان
چکیده
Abstract Two novel fluorescent probes L1 and L2 for recognizing Al 3+ have been prepared by cooperating salicylaldehyde‐derived Schiff base groups onto the upper rim of calix[4]arene. Of these probes, is most effective at , displaying a highly selective fluorescence “on” response with an emission wavelength 478 nm Stokes shift 88 nm. Additionally, probe can form 1 : coordination complex binding constant 2.6×10 10 M −1 . Furthermore, its intensity exhibits good linear relationship concentration within range 2.0×10 −5 to 1.4×10 −4 M, has low detection limit 4.36×10 −7 M.

An Alternative Method for Synthesis of Thermally Stable Aromatic Polyesters Containing Schiff Base Unites
In this paper, an efficient method for synthesis of aromatic polyesters containing schiff base units is described by preparation of two polyesters. These polyesters have been prepared by the reaction of terephthaloyl dichloride on Schiff bases derived from p-hydroxybenzyldehyde and 4,4-diamino diphenyl ether, 4,4-diamino diphenyl methane. The Polymers were characterized by IR, CHNS, thermal...

— Salen type chromium Schiff base complex was synthesized by microwave irradiation. The complex was characterized by UV-visible, FT-IR spectroscopy and EPR spectroscopy. Electrochemical property of chromium complex was tested with the aid of cyclic voltammetry (CV). The synthesized chromium Schiff base complex was electrochemically polymerized and used for the detection of hydroquinone. Chromiu...
