Covalent Organic Frameworks (COFs) Tetraphenylethylene Ligand

used for the synthesis of macromolecules and COFs with photoluminescence and aggregation-induced emission


Overview | Product Information | Related Products


1,2-Bis(4-ethynylphenyl)-1,2-diphenylethene (CAS number 1240785-42-5) features a tetraphenylethylene core with two ethynyl groups. Tetraphenylethylene building blocks are widely used for the synthesis of aggregation-induced emission (AIE) materials. The propeller shape of tetraphenylethylene hinders the ππ stacking and eliminates the aggregation-caused quenching effect. The ethynyl groups enable 1,2-Bis(4-ethynylphenyl)-1,2-diphenylethene to undergo multiple reactions such as Sonogashira coupling reaction and azide-alkyne cycloaddition (click chemistry).

Polydiynes of 1,2-bis(4-ethynylphenyl)-1,2-diphenylethene are prepared from iodination of the ethynyl group followed by a KI-mediated metal-free homo-polycoupling reaction. The polydiynes exhibit UV-tuneable refractive indices (n = 1.77 to 2.11).
