OLED Performance and the Use of a Hole Transport Molecule Dissolved in a High Tg Host Polymer
Abstract:TPD has been dissolved in A435, a high Tg host polymer, in order to inhibit the crystallization of the hole transport molecule. Solid solutions of TPD have been obtained for a TPD content, x, ranging from 25 to 90 wt%. A435 + x TPD films coated onto ITO are stable during at least 72h at 150°C, for TPD contents of 50 wt% and below. OLEDs having the structure: ITO / A435 + x TPD/ Alq3 /Mg have been prepared and measured. Maximum luminances of about 2000 cd/m2 are obtained for x ≥ 50 wt% TPD. The maximum quantum yield of these devices is 1.4%.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
