Polyfluorene

This is the photoluminescence of two very similarly structured polyfluorene derivatives. The one on the left (purple) is a copolymerization of a fluorene derivative, benzene and oxadiazole molecules and the one on the right (light green) has the structure directly below this image.

This polyfluorene derivative photoluminesces light green (the vial on the right in the image above), the alcohol (-OH) side chains can participate in ESIPT with the neighboring oxadiazole nitrogens causing a red-shifted emission. The meta-linkages in the backbone impart solubility in lieu of multiple side chains.

Polyfluorenes are a class of polymeric materials. They are of interest because similar to other conjugated polymers, they are currently being investigated for use in light-emitting diodes, field-effect transistors, and plastic solar cells. They are not a naturally occurring material, but are designed and synthesized for their applications. Modern chemistry has enabled adaptable synthesis and control over polyfluorenes that has facilitated use in many organic electronic applications.
