Summary: Electromagnetic wave multiplexing, especially for spatial-frequency multiplexing, is important for ultrathin multifunctional interfaces and high-capacity information processing and communication. However, it is challenging to achieve with passive and compact wave elements due to the exclusive coupling between wave excitation and scattering channels. In this study, a spin-momentum multiplexed paradigm called a super-reflector is proposed, enabling control of both retroreflections and anomalous reflections. By multiplexing four channels connecting two spin states and three spatial frequencies, a total of twelve channels are engineered, with five degrees of freedom in circular polarization Jones' matrix. Experimental verification has been conducted, showcasing twelve reflected beams with high efficiency exceeding 90.6%. This strategy opens up possibilities for angle multiplexing and angle-resolved metadevices.

Summary: In this study, a catalyst-free thiol-yne click reaction was used to develop sulfur atom-based photosensitizers (PSs) with enhanced intersystem crossing (ISC) effects. The introduction of a tetraphenylpyrazine-based aggregation-induced emission (AIE) unit was advantageous for promoting ISC in the aggregated state. Furthermore, the sulfur atom electron donor, double-bond pi bridge, and AIE electron acceptor created a donor-pi-acceptor (D-pi-A) molecular system with excellent two-photon excitation properties. The resulting polymer nanoparticles exhibited exceptional in vitro two-photon-excited PDT towards cancer cells, showing great potential for deep-tissue disease therapy.

Summary: All current commercial colors are pigment-based, which have limitations such as fading, instability in atmosphere, and environmental toxicity. The development of artificial structural coloration has been hindered by the lack of design ideas and impractical nanofabrication techniques. However, a self-assembled subwavelength plasmonic cavity has been presented as a solution to these challenges, allowing for angle and polarization-independent vivid structural colors. This platform, fabricated through large-scale techniques, offers a lightweight paint option with full coloration using just a single layer of pigment.
