Ultrastable Self‐Cross‐linkable Electro‐Optic Materials Based on a Bisanthracene Scaffold

open access: yesAdvanced Electronic Materials, EarlyView.
A novel bisanthracene‐based self‐cross‐linkable electro‐optic chromophore (TD2) is developed. TD2 exhibits a high r33 of 141 pm/V and a cross‐linked Tg up to 195 °C, retaining 99.75% of its initial EO response after 500 h at 85 °C, showing record‐high thermal stability for single‐molecule self‐cross‐linking EO materials.

Ruthenium-catalyzed azide-alkyne cycloaddition: Scope and mechanism

open access: yes, 2008
The catalytic activity of a series of ruthenium(II) complexes in azide-alkyne cycloadditions has been evaluated. The [Cp*RuCl] complexes, such as Cp*RuCl(PPh3)2, Cp*RuCI(COD), and Cp*RuCl(NBD), were among the most effective catalysts.

Portable Detection of Copper Ion Using Personal Glucose Meter

open access: yesSensors
A simple and sensitive method for Cu2+ detection was developed using the Cu+-catalyzed alkyne–azide cycloaddition reaction, Fe3O4 magnetic nanoparticles (MNPs) as the reaction platform, and a portable blood glucose meter (PGM) as the detection method ...

Copper-catalyzed alkyne-azide cycloaddition for the functionalization of fullerene building blocks

open access: yes, 2011
In this paper, we report our ongoing progress in the preparation of fullerene-azide or fullerene-alkyne building blocks, allowing their further chemical transformation under the copper-catalyzed alkyne-azide cycloaddition (CuAAC) reaction conditions.

Enantioselective Rh-Catalyzed Azide-Internal-Alkyne Cycloaddition for the Construction of Axially Chiral 1,2,3-Triazoles

open access: yes, 2022
Significant advances have been achieved for the construction of chiral skeletons containing 1,2,3-triazoles via transition-metal-catalyzed asymmetric azide–alkyne cycloaddition; however, most of them have been limited to terminal alkynes in the synthesis

Tuning the optical properties of BODIPY dye through Cu(I) catalyzed azide-alkyne cycloaddition (CuAAC) reaction

open access: yes, 2012
Borondipyrromethenes (BODIPY) are a class of fluorescent dyes whose fluorescence quantum yields are generally high and independent of the solvent. In this paper, we report the synthesis of a new type of BODIPY compound that carries an azido group on the ...
