Abstract

Organic hole-transporting molecules were infiltrated into inorganic mesochannels via hexagonally ordered nanopores that are open at the edge side of mesoporous silica (MS) nanolayers prepared using a block copolymer template. This organic-molecule-infiltrated MS nanolayer was used as a hole injection/transport layer for hybrid organic light-emitting devices (HOLED) for improving the device stability. The result showed that the efficiency of HOLED is within reach of that of conventional devices, promising further improvement by the thickness control.

摘要

通过六方有序纳米孔将有机空穴传输分子渗透到无机介孔通道中，这些纳米孔在使用嵌段共聚物模板制备的介孔二氧化硅（MS）纳米层的边缘侧是开放的。这种有机分子渗透的MS纳米层被用作混合有机发光器件（HOLED）的空穴注入/传输层，以提高器件稳定性。结果表明，HOLED的效率已接近传统器件，有望通过厚度控制进一步提高。
