Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes
Advanced Materials Technologies, EarlyView.We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Synthesis and antimicrobial activity of some new pyrrole derivatives
Bulletin of the Chemical Society of Ethiopia, 2012 New pyrrole derivatives were synthesized and structures were confirmed by IR, 1H NMR, 13C NMR, mass spectra, and elemental analyses data. The reaction was performed by using ordinary condensation type, which enabled to easy work-up and good yield ...

Advanced Optical Materials, EarlyView.Whispering‐gallery‐mode microresonators with sharp resonant peaks enable photonic barcoding. Similar to a chameleon, a rare‐earth‐free microcavity with π‐conjugated PAHs enables visibleto‐near infrared color generation from a single microbead. The unique resonat emission (spectral barcode) can be dynamically transformed via excitation wavelength change,

Advanced Optical Materials, EarlyView.An organic–inorganic mixed excited state is designed and demonstrated by combining the metal–metal and π–π interactions within a supramolecular Pt2–pyrene assembly. Directional orbital overlap between the Pt and carbon atoms gives rise to a long‐lived triplet emission, strong emission polarization, exciton–exciton annihilation, and efficient exciton ...

Phototunable Polarization Volume Gratings Driven by Chiral Hydrazone Switches
Advanced Optical Materials, EarlyView.Chiral hydrazone photoswitches incorporated into polarization volume gratings enable light‐driven, reversible modulation of optical properties. UV and blue light irradiation reversibly alter the hydrazone isomer ratio, leading to tunable diffraction efficiency and spectral response across the visible spectrum.

Advanced Robotics Research, EarlyView.A flexible liquid‐crystalline electrolyte membrane via in situ photopolymerization of a phosphate‐functionalized mesogen, ionic liquid, and diacrylate monomer is developed. The resulting smectic B (SmB)‐phase structure enables 2D ion transport with high conductivity (10−4 S cm−1).
