Hole injection/transport materials derived from heck and sol-gel chemistry for application in solution-processed organic electronic devices

An organosilicate polymer, based on N,N′-diphenyl-N,N′-bis(4- ((E)-2-(triethoxysilyl)vinyl)phenyl)biphenyl-4,4′-diamine (TEVS-TPD) with extended conjugation between the Si atom and the aromatic amine, was prepared under mild conditions via sequential Heck and sol-gel chemistry and used as an alternative to poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), the most widely used planarizing hole injection/transport layer in solution-processed organic electronic devices. Spin-coating TEVS-TPD polymer solutions yield defect-free, uniform, thin films with excellent adhesion to the ITO electrode. Upon thermal cross-linking at 180 C, the cross-linked polymer exhibits excellent solvent resistance and electrochemical stability. Solution-processed organic light emitting diode (OLED) devices using iridium-based triplet emitting layers and cross-linked TEVS-TPD films as a hole injection/transport layer show significantly improved performance including lower leakage current, lower turn-on voltage, higher luminance, and stability at high current density, as compared to the control device prepared with PEDOT:PSS.

New semiconductors based on triphenylamine with macrocyclic architecture: Synthesis, properties and applications in OFETs

Two novel macrocycles based on triphenylamine (TPA) have been synthesized by McMurry coupling reactions. The cyclic compound 2 consisted of two triphenylamines linked with ethylene bridges bearing two n-butyl chains. The compound 3 was based on N,N,N′,N′-tetraphenylbenzidine (TPD) units with macrocyclic architecture. They were fully characterized by cyclic voltammetry, UV-vis absorption and self-assembly properties. The crystal structure of 2 was determined by X-ray analysis. Atomic force microscope and scanning electron microscope images showed that compound 3 could form interesting fiber-like nanostructures by self-assembly. Both of the compounds can be used as active layers for p-type OFETs. The OFET device based on 2 prepared via a vacuum-deposit method gave a mobility of 2.3 × 10 -3 cm2 V-1 s-1 and a current on/off ratio of 105. High quality thin films of 3 were fabricated by spin coating from solution, and gave a mobility of 2.0 × 10-3 cm2 V-1 s-1 with a current on/off ratio of 2 × 105. The results showed that the TPA derivatives with cyclic structures might fit better for OFETs. They may provide promising new choices for organic semiconductors. The Royal Society of Chemistry 2007.
