Influence of solution- and thermal-annealing processes on the sub-nanometer-ordered organic-organic interface structure of organic light-emitting devices.
Solution- and thermal-annealing processed organic-organic interface structures were investigated by neutron reflectometry. We revealed the true picture of interfaces, a polymer hole-transporting layer - a small molecule light-emitting layer - a small molecule electron-transporting layer, and discussed influences of those interface structures on organic light-emitting devices.
