Abstract
Tirphenylamine is good a hole transport material with electrochemistry activity. We hope to use this moiety to synthesis triphenylamine derivatives to improve the performance of OLED, including red light emitting materials, hole transport materials. n chapter 2, the physical of red light emitting PCF dye 1 was discussed with electrochemistry, Förster energy transfer, and OLED devices. The dye-doped organic light-emitting diode shows red electroluminescence with the efficiency of 2.9 cd/A at 100 cd/m2 and maximum brightness of 62000 cd/m2. This chapter had published in Organic Lett. 2006, 8, 2623-2626n chapter 3, we had synthesized a photo-labile organic semi-conducting polymer 1 and polymer 2 with triphenylamine moiety with photo resistance type property. The triphenylamine group served as two functions: (1) cross-linking the polymer through electro-polymerization (2) hole transport material. After UV illumination, the polymer can be selectivity dissolution; we also demonstrated an image with PLED device. This chapter had published in Chemistry of Materials. 2008, 20, 5816-5821.inally, We use nitroxide SAM to serve as surface initiator, then growth triphenylamine polymer brush on ITO . After electro-polymerization, triarylamine polymer brushes can be dimerized and cross-link for hole transport enhancement. Surface analysis of cyclic voltammetry, UV-Vis absorption, water contact angle, and SEM had been studied in this chapter. The PLED device was optimized to 16200cd/m2 and 20.9cd/A. Through photo oxidation, polymer brushes can be selectively degradation to prepare a patterned PLED emitting device.
