Conducting polymers have emerged as promising active materials for metasurfaces due to their electrically tunable states and large refractive index modulation. However, existing approaches are often limited infrared operation or single-polymer systems, restricting versatility. In this Letter, we present organic featuring dual conducting polymers, polyaniline (PANI) poly(3,4-ethylenedioxythiophene) (PEDOT), achieve contrasting dynamic optical responses at visible frequencies. Sequential electrochemical polymerizations locally conjugate subwavelength-thin layers of PANI PEDOT onto preselected gold nanorods, creating electro-plasmonic antennas with distinct optoelectronic properties. This dual-polymer approach enables metasurface pixel control without individual electrode routing, thereby simplifying designs. The exhibit dual-channel functions, including anomalous transmission holography, through the redox-state switching both polymers. Our work underscores potential applications, offering a pathway advanced reconfigurable devices

In the field of organic electronics and optics, there is rapidly growing interest in enhancing both charge transport ion properties semiconductors, particularly light recent emerging technologies such as electrochemical transistors (OECTs) switchable nanoantennas. Herein, we propose a universal method for internalizing ionic conventional polymer semiconductors. The incorporation tetrafluorophenyl azide-based photochemical cross-linker with tetraethylene glycol bridge into poly(3-hexylthiophene) (P3HT) significantly enhances performance operational stability ion-gating devices. Changes characteristics OECTs cross-linked P3HT are minimal even after 100 cycles operation; moreover, exhibit faster switching properties. addition, enhanced doping efficiency allows clear observation plasmon resonances nanostructured, highly doped P3HT. We believe that proposed technique abilities can be applied to various ion-based semiconductor applications.

Abstract Dynamically switchable surface plasmons in conducting polymers constitute an emerging route towards intelligent metasurfaces, but polymer have so far suffered from weak resonances with low quality factors ( Q < 1-2). Here, we address this by nonlocal coupling of individual poly(3,4-ethylenedioxythiophene) (PEDOT) nanoantennas through collective lattice (CLR) periodic arrays (with resonance wavelengths around 2.0-4.5 μm). The results show that careful tuning CLR matching conditions enables organic plasmonic up to 12. Angle-dependent extinction spectra connect the enhancement radiative diffractive effects. Furthermore, strength between nanoantenna units and could be modulated via redox reactions, enabling narrow CLRs reversibly switched large modulation depth (between 7% 45% extinction). By improving , study circumvents previous limitations plasmonics shows feasibility for practical applications active metasurfaces nano-optics.
