Abstract
A process for preparing a substituted or unsubstituted 9,10-diaryl anthracene including reacting a substituted or unsubstituted anthracene with a halogenating agent to yield a halogenated anthracene, and reacting the halogenated anthracene with an aryl boronic acid or a boronic ester to yield the substituted or unsubstituted 9,10-diaryl anthracene is disclosed. An electroluminescent device comprising a light-emitting layer comprising the substituted or unsubstituted 9,10-diaryl anthracene is also disclosed.

A process for preparing a substituted or unsubstituted 9,10-diaryl anthracene comprising:
- reacting a substituted or unsubstituted anthracene with a halogenating agent to yield a halogenated anthracene, wherein the halogenating agent comprises an oxidizing agent;
- reacting the halogenated anthracene with a palladium complex to yield a palladium intermediate, wherein the palladium intermediate undergoes transmetallation with a boronic ester to yield the substituted or unsubstituted 9,10-diaryl anthracene,
- concentrating the substituted or unsubstituted 9,10-diaryl anthracene under reduced pressure, and
- purifying the substituted or unsubstituted 9,10-diaryl anthracene by flash chromatography first with hexane then with dichloromethane, and by sublimation at 320° C.
