Usage

Uses

Used in OLED Industry:
4,4'-Bis(2,2-diphenylvinyl)-1,1'-biphenyl is used as a blue host-emitting material for enhancing the performance of OLEDs. Its application in this industry is due to its ability to effectively manipulate the Schottky energy barrier between the ITO (indium tin oxide) and the emitting layer. This manipulation significantly improves the hole-injection, current, and luminance efficiencies of OLEDs, as well as their overall stability.

Classification

Hole-injection materials, Hole-transporting materials, Blue light-emitting materials, Host materials, Organic light-emitting diodes (OLEDs), Organic electronics.

Triarylethene-based extended π-systems: Programmable synthesis and photophysical properties

(Chemical Equation Presented) On the basis of an efficient Pd-catalyzed triarylation to a vinylsilane platform, four types of structurally well-defined triarylethene-based extended π-systems have been prepared very rapidly. From a compound library constructed by the present method, it was possible to find a number of interesting fluorescent materials, as well as interesting fluorescent properties such as aggregation-induced enhanced emission. A useful method for the rapid synthesis and property evaluation has also been developed.
