A series of new hexaalkoxytriphenylenes having 1, 2, or even 3 lateral attached acrylate
moieties as polymerizable groups were synthesized and characterized. The conditions for the photopolymerization of these monomers in thin film were evaluated and tested. The bisacrylates and trisacrylates
were used to build insoluble networks. When a mask is used during the irradiation, patterned films
could be prepared. The polymerization reaction was controlled by GPC and FTIR spectroscopy. The
networks and patterned structure were confirmed by UV spectroscopy, surface profiles, and SEM
photographs. Since hexaalkoxytriphenylenes are known as excellent photoconductors, the photopolymerized films were utilized as hole transport layers in two layered organic light-emitting diodes (LEDs) with
Alq3. The LED preparation, characterization, and performance are described.
