Despite great progress in developing mode-selective light emission technologies based on self-emitting materials, few rewritable displays with mode-selective multiple light emissions have been demonstrated. Herein, we present a rewritable triple-mode light-emitting display enabled by stimuli-interactive fluorescence (FL), room-temperature phosphorescence (RTP), and electroluminescence (EL). The display comprises coplanar electrodes separated by a gap, a polymer composite with FL inorganic phosphors (EL/FL layer), and a polymer composite with solvent-responsive RTP additives (RTP layer). Upon 254 nm UV exposure, a dual-mode emission of RTP and FL occurs from the RTP and EL/FL layers, respectively. When a polar liquid, besides water, is applied on the display and an AC field is applied between the coplanar electrodes, EL from the EL/FL layer is triggered, and the display operates in a triple mode. Interestingly, when water is applied to the display, the RTP mode is deactivated, rendering the display to operate in a dual mode of FL and EL. By manipulating the evaporation of the applied polar liquids and water, the mode-selective light emission of FL, RTP, and EL is rewritable in the triple-mode display. Additionally, a high-security full-color information encryption display is demonstrated, wherein the information of digital numbers, letters, and Morse code encoded in one optical mode is only deciphered when properly matched with that encoded in the other two modes. Thus, this article outlines a strategy to fulfill the substantial demand for high-security personalized information based on room-temperature multi-light-emitting displays.

We report geometry-controlled organic ferroelectric field-effect transistors (FeFETs) that combine patterned poly(vinylidene fluoride–trifluoroethylene) (PVDF–TrFE) ferroelectric lines with selectively grown single-crystalline 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-PEN) channels. The patterned PVDF–TrFE layers, fabricated via soft-lithography-assisted floating-transfer printing followed by melt-quenching and annealing, exhibit well-oriented β-phase crystallinity with stable polarization. Solvent-directed deposition of TIPS-PEN using a toluene/dodecane cosolvent enables anisotropic, ribbon-shaped single crystals precisely aligned along the ferroelectric geometry. The structural confinement of ferroelectric domains and the single-crystal semiconductor channel act synergistically to yield well-defined polarization hysteresis, higher ON current, and suppressed gate leakage. Surface-energy-guided growth studies on self-assembled monolayer-modified and topographic substrates reveal that selective nucleation occurs when the substrate surface energy matches or exceeds the solvent surface tension. These findings demonstrate a simple, low-temperature, and scalable approach for realizing geometry-controlled FeFETs with enhanced characteristics through the integration of ferroelectric domain alignment and single-crystal transport.

top-gate transistors and logic circuits, demonstrating its potential for scalable and large-area high-performance 2D electronics.

) nanosheets sandwiched between two liquid metal electrodes. The study revealed that two types of MXene with positive and negative surface potentials incorporated into p- and n-type ionoelastomers, respectively, facilitated the diffusion of mobile ions. This resulted in an enhanced current rectification of an ionic diode. The rectification of an ionic junction is further increased upon NIR exposure to the device due to the photothermal energy conversion of MXene. A facile control of the rectification ratio with both exposure time and power of NIR enabled the development of a switchable ionic logic gate. Herein, the AND-to-OR gate transition was reversibly manipulated by NIR exposure and device cooling programmed to the two ionic junctions in series.
