Tetraphenylethylene Usage And Synthesis

Chemical Properties

WHITE TO LIGHT BEIGE CRYSTALLINE POWDER

Uses

1,1,2,2-Tetraphenylethylene is used as a reagent in the synthesis of a dynamic covalent imine gel as a luminescent sensor. Studies show that 1,1,2,2-Tetraphenylethylene (TPE) can assemble into self-luminescent nanoparticles which are part of a drug delivery system that shows aggregation-induced emission and can be easily tracked in cells.

Purification Methods

Crystallise the ethylene from dioxane or from EtOH/*C6H6. Sublime it under high vacuum. [Beilstein 5 H 743, 5 IV 2780.]
