文摘

Highly efficient polyfluorene copolymer PFOPV-based PLEDs were reported. MEL study joint by time-resolved spectra were employed in measurements. CT states between PFO and MEH-PPV components contribute largely to the EL emission. Triplet CT states were harvested to generate singlets through RISC process.
