General description

Poly[9,9-bis-(2-ethylhexyl)-9H-fluorene-2,7-diyl] (PFO) is a polyfluorene based conductive liquid crystalline material that can be used as a light emitting material. It forms a semiconducting layer to enhance the electroluminescence (EL) and performance of the photonic and optoelectronic devices.
Light-emitting, conjugated polymer exhibiting blue photo- and electroluminescence.

Application

PFO forms a π-conjugating polymeric system that can produce blue EL devices which include organic light emitting diodes (OLEDs), optical fibers and molecular electronic devices.

Dr. Tan and researcher introduce recent trends in Self-healing Soft Electronic Materials and Devices. The emergence of smart, functional SHPs will be highly beneficial to the advancement of the next-generation self-healing soft electronic devices. Autonomously self-healing devices could help to minimize the need for repair or replacement of electronics and machines, potentially reducing the cost of materials and reducing electronic waste.
