New sensitive moisture getter system by using aluminium complex and polyacetylene containing silyl group for display.
In this study, a novel moisture getter was fabricated from a new desiccant triethylaluminum [TEA] and a porous material poly(1-trimethylsilylpropyne) [PTMSP] as a binder and then was applied to organic light-emitting diode (OLED). After forming a film of 1.5 cm x 2.0 cm with 50 mg of PTMSP by a film-casting method, its property was measured. As a result, PTMSP (Mn:50 K) created a film with a relatively high porosity. PTMSP (60%) and TEA (40%) were mixed to fabricate a getter system with a good transmittance of over 80%. The fabricated getter, adopted in a OLED device, showed excellent features, as a level of commercialization: 490-hour shelf lifetime under the conditions of 60 degrees C and 90% RH.
