transistor (OLET) integrates the logic
function of a field-effect transistor (FET) with electroluminescence
of a light-emitting diode (LED) into a single device. This has the
potential to play an important role in smart displays, electrically
pumped organic laser, and other flexible electronic devices. For achieving
high-performance solution-processed OLET, three semiladder copolymersTPTI-CC,
TPTI-C, and TPTI-Fwere developed. It was found that variation
in the chemical structure lead to significant differences in energy
level, emission color, and intermolecular aggregation. High photoluminescence
quantum yields (PLQY) was obtained in these three polymers. Solution-processed
trilayered OLET devices were fabricated, which exhibited strong electroluminescence,
balanced charge mobility, and external quantum efficiency (EQE) of
2.8%.
