However, it remains a great challenge to obtain with high carrier mobility photoluminescence quantum yield simultaneously. Here, new design strategy is reported emissive ambipolar even n‐type by introducing perfluorophenyl groups into polycyclic aromatic hydrocarbons such as perylene anthracene. The results reveal that 3,9‐diperfluorophenyl ( 5FDPP ) exhibits the semiconducting property hole electron mobilities up 0.12 1.89 cm 2 V −1 s , of 55%. One crystal forms 5FDPA blue emission an 52% simultaneously shows 2.65 which highest value among semiconductors.

Despite the remarkable synthetic accomplishments in creating diverse polycyclic aromatic hydrocarbons with B-N bonds (BN-PAHs), their optoelectronic applications have been less exploited. Herein, we report achievement of high-mobility organic semiconductors based on existing BN-PAHs through a "periphery engineering" strategy. Tetraphenyl- and diphenyl-substituted BN-anthracenes (TPBNA DPBNA, respectively) are designed synthesized. DPBNA exhibits highest hole mobility 1.3 cm2 V-1 s-1 field-effect transistors, significantly outperforming TPBNA all reported BN-PAHs. Remarkably, this is first BN-PAH over 1 , which benchmark value for practical as compared amorphous silicon. Furthermore, high-performance phototransistors also demonstrated, implying high potential when strategy implemented.

Metals have been the dominant plasmonic materials for decades, but they suffer from limited tunability. By contrast, conducting polymers offer exceptional tunability and were recently introduced as a new category of dynamic materials. Their charge carrier density can be drastically modulated via their redox state, offering reversible gradual transitions between optically metallic dielectric behavior. Nanoantennas made therefore reversibly turned off on again. This enables phase gradient metasurfaces with tunable functionalities, holding promise applications such video holograms. In this Perspective, we discuss emergence polymer plasmonics research direction, including recent developments, remaining challenges, opportunities future research. We hope that Perspective will encourage more researchers to join journey contribute toward rapid development interdisciplinary field.
