Copolymer gets blue light

Polymer light-emitting diodes (PLEDs) are promising for cheap, large, flatpanel displays. Systematic variation of the polymer chemical structure allows luminescent properties to be adjusted. Polyfluorenes (PFs) can be used in blue PLEDs and exhibit high photoluminescence (PL) and electroluminescence...

Description
Summary:Polymer light-emitting diodes (PLEDs) are promising for cheap, large, flatpanel displays. Systematic variation of the polymer chemical structure allows luminescent properties to be adjusted. Polyfluorenes (PFs) can be used in blue PLEDs and exhibit high photoluminescence (PL) and electroluminescence (EL) efficiencies. However, they exhibit an undesirable green emission on extended device operation or after thermal annealing during device manufacture. A team from the National Chiao Tung University and National Tsing Hua University in Taiwan has overcome this difficulty by synthesizing a fluorene-based copolymer called PFA-OXD LWu et al., Macromolecules (2005) 38 (22), 9028].
