Organometallic Magnesium Complex with Aggregation Induced Emission Properties: Synthesis, Characterization, and Fluorescent Fibers Applications

Abstract

In this work, a novel organomagnesium complex with outstanding aggregation induced emission (AIE) properties is synthesized using dibenzoylmethane (DBM) as the ligand. The structure of the complex is confirmed to be one magnesium ion coordinated to the dione groups of two DBM molecules, and the magnesium ion adopts a distorted octahedrally geometry. The obvious emission is found for Mg(DBM) 2 powder and not in the solution, making this the first reported organomagnesium complex with AIE property. The properties of the complex were investigated by using UV-vis absorption and fluorescence emission spectroscopy, cyclic voltammetry, and density func-tional theory calculations. Moreover, the Mg(DBM) 2 solution dispersed in filter paper was is colorless, which may be made into a convenient anti-counterfeiting and encryption tool. Mg(DBM) 2 /alginate fibers were prepared by wet-spinning process and further processed into paper, which can be used in the fields of sensors, anti-counterfeiting, and encryption. Sweat contains a wealth of chemical information that could potentially indicate the body's deeper biomolecular state. The prepared fluorescent fibers were used to detect sweat due to its nontoxic, low-cost efficient and fast response to analytes.

Custodial symmetry violation in scalar extensions of the standard model*

“…[94] studied the compatibility of the spectrum preferred by the CDF II W mass with other EWPOs and Higgs precision data in an inert complex triplet extension (with hypercharge ) of the SM, and Ref. [95] studied both complex and real triplet extensions by directly performing a global fit to EWPOs with CDF II via Bayesian analysis. Both references also discuss some related collider phenomenology.…”

Advances in Non-Electrochemical Sensing of Human Sweat Biomarkers: From Sweat Sampling to Signal Reading

“…After the liquid reaches the detection area, the concentration of the target substance is analyzed using non-electrochemical methods such as colorimetry, fluorescence, and spectroscopy [104,121,133]. Colorimetry analyzes the concentration of the target substance by observing the color change of the colorimetric reagent without the need for an external light source, but it has a limited detection range [106,218]. Fluorescence, requiring external light, measures intensity changes for concentration calculation, enhancing sensitivity and detection speed [52,53,218,219].…”

Preparation of Thermosensitive Fluorescent Polyacrylamide Nanofiber Membrane and Visual Temperature Sensing

“…When the special light source disappears, the fiber can restore its own color. Thus, to date, fluorescent fibers have attracted widespread attention based on their potential application in different fields because of their unique photochromic properties [ 1 , 2 , 3 ]. Generally, fluorescent fibers are fabricated using three common methods: melt- [ 4 , 5 ], wet- [ 6 , 7 ] and electrospinning [ 8 , 9 ].…”
