Abstract
The invention discloses a method for detecting hydroquinone by electrochemiluminescence based on aggregation-induced luminescence Cd-MOF, comprising the following steps: one, preparing Cd-MOF material; two, mixing Cd-MOF material with a co-reactant; and three, establishing and applying a hydroquinone sensor. The invention uses organic ligands TPPE and CdCl2 with aggregation-induced luminescence effect to prepare a self-luminescent Cd-based metal organic framework Cd-MOF with a rigid and directional structure through coordination, effectively constrains the intramolecular free rotation of TPPE and inhibits non-radiative relaxation, and provides a fast and simple strategy for MOF synthesis. Meanwhile, the prepared Cd-MOF has significant ECL performance, and an ECL sensor sensitive to hydroquinone is constructed based on the Cd-MOF, thereby providing a fast, highly sensitive and low-cost detection method for the detection of hydroquinone.
