    Organic light-emitting transistors (OLETs) combine the light-emitting and gate-modulated electrical switching functions in a single device. Over the past two decades, progress has been made in developing new fluorescent semiconductors and device engineering to improve the properties of OLETs. In this paper, we give a brief review of the achievement and disadvantages of the present polymer-based OLETs, while highlighting the recent developments in semi-ladder polymers from our lab for new electroluminescent materials. The special folded molecular structures and unique aggregation states make these polymers suitable for exploration as OLET materials. A short conclusion is provided with a discussion on the challenges and future perspectives in this field.

    A critical issue in developing high-performance organic light-emitting transistors (OLETs) is to balance the trade-off between charge transport and light emission in a semiconducting material. Although traditional materials for organic light-emitting diodes (OLEDs) or organic field-effect transistors (OFETs) have shown modest performance in OLET devices, design strategies towards high-performance OLET materials and the crucial structure–performance relationship remain unclear. Our research effort in developing cross-conjugated weak acceptor-weak donor copolymers for luminescent properties lead us to an unintentional discovery that these copolymers form coiled foldamers with intramolecular H-aggregation, leading to their exceptional OLET properties. An impressive external quantum efficiency (EQE) of 6.9% in solution-processed multi-layer OLET devices was achieved.
