PFO-co-MEH-PPV is a co-polymer consisting of alternating 9,9-dioctylfluorenyl and 2-methoxy-5-(2-ethylhexyloxy)-1,4- phenylenevinylene (MEH-PPV) repeating units in its main backbone structure.
Owing to its capability of harvesting the energy from non-emissive triplet states, PFO-co-MEH-PPV is a reverse intersystem crossing (RISC) polymer which can be used in solution processable, non-doped, highly efficient OLED devices.
PFO-co-MEH-PPV can also be used for polymer lasers with the demonstration of a relaxation oscillation and a picosecond pulse generation.
