Abstract
我們提出一種具水/醇類可溶解性的電子注入/電洞阻擋複合層，其包含接枝有冠醚側鏈之共軛高分子，以及具有電洞阻擋功能的高分子，該共軛高分子具有為該冠醚所穩定的擬金屬狀態金屬離子以降低電子注入的能障及促進電子傳遞功能。此複合層能提升利用對水氧具高度穩定性的金屬(如鋁與金)做為陰極之高分子發光二極體OLED的效能。
An water/alcohol soluble electron-injection/hole-blocking composite layer contains a conjugated polymer grafted with a side chain crown ether and with pseudo-metallic state of metal-ion stabilized by the crown ether (to reduce electron-injection barrier and facilitate electron transport), and a polymer with hole-blocking function. This composite layer is able to improve the performance of an organic light emitting diode with oxygen- and moisture-stable cathode (such as Al and Au).
