Both soluble and insoluble conjugated polymers have advantages and disadvantages for the construction of light-emitting diodes (LEDs). A route is reported fo the formation of optical quality films of insoluble (I) MEHPV, a poly(phenylenevinylene) derivative whose soluble form is widely used in single-layer devices. The incorporation of 1-MEHPPV into a multilayer device is described, in which the electron-transport/holeblocking layer was deposited on top of the 1-MEHPPV layer from a solvent in which the standard soluble MEHPPV should dissolve.
