Light-emitting reactive mesogens are promising materials for photolithographically processable organic light-emitting
diodes (OLEDs). We study the photopolymerization of a fluorene-based mesogen with methacrylate photoreactive
groups. We find that there is no significant change in the photoluminescence quantum efficiency when the mesogen is
photopolymerized in a glovebox with oxygen and water concentration at < 20 parts per million. There is significant
quenching of luminescence when the photopolymerization is carried out in a less controlled environment. A real-time
measurement is used to monitor changes in the FTIR spectrum of the compound during polymerization. No photo-initiator
is added to the mesogen suggesting that the photo-polymerization is self-initiated by the chromophore. We show
that the self-initiation does not proceed by fragmentation of the aromatic core and suggest an alternative mechanism.
