講演題目：Organic Syntheses and Properties of Stabilized Conjugated Polymers for AMOLEDs

Abstract:

Conjugated polymers with a stabilized blue emission are of importance for the realization of full-color displays using polymer light-emitting diodes. Several types of novel conjugated polymers with stabilized electroluminescence (EL) emission are reported. Poly(2,6-(4,4-bis(2-ethylhexyl)-4H-cyclopenta[def]phenanthrene)) (PCPP) is a new class of blue-emitting polymers utilizing a new back-bone. This material emits a stabilized, efficient blue EL without exhibiting any peak in the long wavelength region (green region) even after prolonged annealing for 18 hours at an elevated temperature of 150^oC in air. In PININE, the vinylene group was cyclized using two 5-membered rings to prevent the oxidation of the vinylene group. While poly(p-phenylenevinylene) derivatives show significantly blue-shifted and decreased peaks of UV-vis, blue-shifted maximum peaks of photoluminescence (PL) after irradiation with white light in air, and blue-shifted maximum peaks of EL after operation of the device, PININE shows stable spectra of UV-vis, and PL, and EL under the same conditions.
