General description
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". Hole transport organic materials allow perfect energy level alignment with the absorber layer and therefore efficient charge collection, are prone to degradation in ambient conditions.Click here for more information.
Application
PFO exhibits excellent luminescent properties, making it particularly valuable as a light-emitting polymer. It is commonly used as an active material in the development of blue and green organic light-emitting diodes (OLEDs) and displays. It has the ability to confine excitons within its polymer chain, allowing for efficient energy transfer and emission of light which property is crucial in efficient OLEDs and other optoelectronic devices. It can be used as a hole transport layer or electron transport layer in organic electronic devices such as OFETs, sensors, and other thin-film devices.
PFO is a highly-fluorescent conjugated hole transport polymer material (HTM) that generates a blue light. It has wide applications in organic light-emitting diodes (OLED), organic photovoltaic (OPV), diagnostics and separation of semiconducting single walled carbon nanotubes. It was originally reported as host (and Ir(HFP)3 as the guest) in high-performance electrophosphorescent light-emitting diodes (LEDs) in 2003. PFO use in electron transport layer in OPV enables both high device fill-factor and power conversion efficiency of photovoltaic devices. PFO exhibits extraordinarily large cross-sections for two-photon excitation (as high as 105 GM19), which means that it is promising for use in dual O2 and pH mapping using two-photon-based imaging techniques. It was reported in highly stable and sensitive imaging systems (eg. intracellular fluorescence resonance energy transfer, FRET, and electrochemiluminescence immunosensor) and pH sensing. Further, a recent review outlined the capability of PFO to selectively wrap and separate semiconducting singlewalled carbon nanotubes (s-SWCNTs) as a promising simple method to disperse and separate s-SWNTs. Compared with devices based on traditional semiconductors (e.g., Si), this would enable scalable, smaller, flexible and stretchable devices with lower power consumption, and faster switching speed thanks to unique s-SWCNTs properties.

In the past two decades, single-walled carbon nanotubes (SWNTs) have been explored for electronic applications because of their high charge carrier mobility, low-temperature solution processability and mechanical flexibility. Semiconducting SWNTs (s-SWNTs) are also considered an alternative to traditional silicon-based semiconductors.
