Summary: A series of TEMPO@PCN-222 composite photocatalysts were developed by coordinating different amount of 4-carboxy-TEMPO with the secondary building units of PCN-222. Visible-light irradiation enables the transfer of photogenerated holes in the highest occupied molecular orbital of PCN-222 to TEMPO, significantly increasing the photosynthesis of bioactive (iso)quinolones. With an outstanding catalytic stability and substrate tolerance, TEMPO@PCN-222 exhibits a yield of 86.7% for 1-methyl-2-quinolinone, over four times higher than PCN-222 (21.4%). This study provides a new route for constructing composite photocatalysts from abundant starting materials for efficient photosynthesis of high value-added chemicals.

Summary: In this study, we demonstrate theoretically and experimentally a strong and tunable optical anisotropy in epitaxially-grown VO2 thin films. We reveal that these films exhibit an ultra-large birefringence through a combination of temperature-dependent X-ray diffraction, spectroscopic ellipsometry measurements, and first-principle calculations. Moreover, by leveraging the insulator-to-metal transition of VO2, we demonstrate a dynamic reconfiguration of optical properties from birefringent to hyperbolic, opening avenues for multi-functional devices with tunable anisotropy and hyperbolic dispersion.

Summary: We designed a temperature-dependent coating to counteract changes in blackbody radiation distribution caused by temperature, leveraging the nonhysteretic insulator-to-metal phase transition of SmNiO3. Our coating maintains nearly constant thermal radiance at each wavelength within the long-wave infrared atmospheric-transparency window over a temperature range of at least 20 degrees C. It can conceal thermal gradients and transient temperature changes from infrared imaging systems, including those that discriminate by wavelength.
