The present invention relates to novel blue light emitting polytriphenylene dendrimers, methods of preparation and uses thereof.
The present polytriphenylene dendrimers comprise a core unit with linked diphenyltriphenylene repeating units of the following formula (1)
The present invention further provides a method for preparing such dendrimers via a series of Diels-Alder cycloadditions reacting an alkinyl-functionalized compound with a diphenylcyclopentaphenanthrenone of formula (2)
Also provided is a novel method for preparing the diphenylcyclopentaphenanthrenone of formula (2).
