Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) is blended with two different inert UV-cross-linkable matrices to tune the solubility of the solution-processed films. It is found that only 10 wt% of theses matrices is required to make the blend layer insoluble after cross-linking. The addition of only 10 wt% matrix only slightly reduces the hole mobility, whereas the electron transport is not affected. Polymer light-emitting diodes (PLEDs) with an insoluble 90:10 MEH-PPV: matrix blend layer exhibit the same current density and photocurrent as pristine MEH-PPV PLEDs.
