Efficient and Stable Solution-Processed Organic Light-Emitting Transistors Using a High-k Dielectric
We report the development of highly efficient and stable solution-processed organic light-emitting transistors (OLETs) that combine a polymer heterostructure with the transparent high-k dielectric poly(vinylidenefluoride(0.62)-trifluoroethylene(0.31)-chlorotrifluoroethylene(0.7)) (P(VDF-TrFE-CTFE)). The polymer heterostructure comprises of poly[4-(4,4-dihexadecyl-4H-cyclopenta[1,2-b:5,4-b’]-dithiophen-2-yl)-alt-[1,2,5]thiadiazolo[3,4-c]pyridine] (PCDTPT) and Super Yellow as charge-transporting and light-emitting layers, respectively. Device characterization shows that the use of P(VDF-TrFE-CTFE) leads to larger channel currents (approximate to 2 mA) and lower operating voltages (-35 V) than for previously reported polymer based OLETs. Furthermore, the combined transparency of the dielectric and gate electrode, results in efficient bottom emission with external quantum efficiency of approximate to 0.88% at a luminance L >= 2000 cd m(-2). Importantly, the resulting OLETs exhibit excellent shelf life and operational stability. The present work represents a significant step forward in the pursuit of all-solution-processed OLET technology for lighting and display applications.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 19524-06-2. Category: pyridine-derivatives.
