Application

Highly emissive poly(9,9-dioctylfluorenyl-2, 7-diyl) end capped with dimethylphenyl (PFO-DMP) is a conjugated polymer with white light emision, remarkable thermal stability and high photo- and electroluminescence efficiency. PFO-DMP was successfully demonstrated in textile digital printing for organic light emission devices (OLEDs) , as well as in high voltage composite separator in Lithium batteries at high rates and low temperatures.
PFO-DMPP can be used as an active material in the fabrication of LEDs. The modification with dimethylphenyl end-capping groups can enhance the charge injection and transport characteristics, leading to improved device efficiency and stability. It can be used in applications in OPV devices, particularly as a donor material. The end-capping with dimethylphenyl groups can modify the energy levels and molecular packing, impacting the optical and electrical properties. PFO-DMPP can be utilized as an active layer in organic thin-film transistors (OTFTs) due to its improved charge transport characteristics. The end-capping groups help to enhance the carrier mobility and improve the performance of the transistors. This modification can influence the power conversion efficiency of the OPV cells.
