Mesoporous silica nanolayers infiltrated with hole-transporting molecules for hybrid organic light-emitting devices.
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.
