The versatility of light‐emitting conjugated polymers in terms of optoelectronic properties is enormous, but tailoring of other essential properties has been relatively limited. In other fields such a problem would be rectified using material formulations. However, the need to maintain high optoelectronic compatibility between components has hampered such development. In this paper, careful design of electronically compatible materials is demonstrated. Additive molecules that are compatible with a family of luminescent polymers are presented, and their performance in a light‐emitting diode configuration is demonstrated. This formulation is aimed to adjust the glass‐transition temperature, maintain/improve film‐forming ability, and introduce a crosslinking functionality. It is found that, by using electronic formulations, a robust procedure is obtained that could be used to produce waveguide lasers or full‐color displays. The patterning ability is shown via the construction of a single pixel that is half green and half orange.
