The synthesis of a new tetraborylethylene (TBE) is reported, and its application in the preparation of [4+0]-tetraarylethenes (TAEs) is elucidated. TAEs have widespread applications in material science and supramolecular chemistry due to their aggregation-induced emission (AIE) properties. The divergent and stereoselective synthesis of [3+1]-, [2+2]-, and [2+1+1]-TAEs via multiple couplings of vinylboronates with aryl bromides is demonstrated. These couplings feature a broad substrate scope and excellent functional group compatibility due to mild reaction conditions. Facile access to various tetraarylethenes is provided. This strategy represents an important complement to the conventional methods employed for the synthesis of TAEs, and would be a valuable tool for synthesizing TAE-based molecules useful in functional materials, biological imaging and chemical sensing.

METHOD OF DETECTING HUMAN SERUM ALBUMIN IN BIOLOGICAL FLUIDS
-
, (2020/03/23)
A method for human serum albumin (HSA) detection in a biological fluid using small molecule, fluorescent compounds having aggregation-induced emission (AIE) characteristics includes contacting the biological fluid with a fluorescent compound to provide a mixture, irradiating the mixture with ultraviolet light, and determining a presence of human serum albumin when an observable emission is detected. The fluorescent compound binds with human serum albumin in the biological fluid and the binding of the compound with the human serum albumin produces the emission. The biological fluid can be urine. The compounds can be water soluble and can include tetrazole-tagged AIEgens. The present methods can be performed using conventional fluorescent spectrometers, normally present in hospitals, or using an HSA detection device. The HSA detection device is portable and can be used by a patient at home.

, (2019/05/30)
Fluorescent probes for silver ion detection include organic, water-soluble compounds having aggregation-induced emission (AIE) characteristics. The probes can sense or detect silver ions through aggregation or a precipitation reaction between the silver ions and the organic compounds which induces fluorescence. The compounds are acidic, soluble in aqueous phase, and provide low background fluorescence in aqueous solutions.

A novel microporous metal-organic framework (FJU-44), with abundant accessible nitrogen sites on its internal surface, was constructed from the tetrapodal tetrazole ligand tetrakis(4-tetrazolylphenyl)ethylene (H4TTPE) and copper chloride. Notably, the CO2 uptake capacity (83.4 cm3/g, at 273 K and 1 bar) in the activated FJU-44a is higher than most of tetrazolate-containing MOF materials. Particularly, FJU-44a exhibits superior adsorption selectivity of CO2/N2 (278-128) and CO2/CH4 (44-16), which is comparable to some well-known CO2 capture materials. Furthermore, the fixed-bed breakthrough experiment indicates that the postcombustion flue gas flow over a packed column with FJU-44a adsorbents can be effectively separated.

Silver staining, which exploits the special bioaffinity and the chromogenic reduction of silver ions, is an indispensable visualization method in biology. It is a most popular method for in-gel protein detection. However, it is limited by run-to-run variability, background staining, inability for protein quantification, and limited compatibility with mass spectroscopic (MS) analysis; limitations that are largely attributed to the tricky chromogenic visualization. Herein, we reported a novel water-soluble fluorogenic Ag+ probe, the sensing mechanism of which is based on an aggregation-induced emission (AIE) process driven by tetrazolate-Ag+ interactions. The fluorogenic sensing can substitute the chromogenic reaction, leading to a new fluorescence silver staining method. This new staining method offers sensitive detection of total proteins in polyacrylamide gels with a broad linear dynamic range and robust operations that rival the silver nitrate stain and the best fluorescent stains.
