We created light-directed dynamic spheres based on simple azobenzene monomers showing (i) a high yield of reversible trans↔cis photoisomerization and (ii) noticeable phase transition from crystalline to isotropic states under UV light irradiation at ambient temperature.

We present, experimentally and theoretically, a polymer material system that supports optical spatial solitons of circular polarization. We demonstrate one-dimensional circularly polarized dark solitons supported by photoisomerization nonlinearity in a bulk polymer.

Oxazolidinone-functionalized enecarbamates undergo diastereoselective E/Z photoisomerization upon direct and triplet sensitized irradiations with chiral/achiral sensitizers, showing that the enhanced product diastereoselectivity depends on the solvent and temperature.

Upon light irradiation, photochromic materials exhibit drastic changes in absorbance addition to molecular and mechanical changes. In this study, we demonstrated optical trapping of microcrystals a double fiber tweezers system combined with two external lights for photoisomerization observed the force by photoisomerization. situ photoisomerizations single crystal trapped were performed thrice r...

Photoisomerization of a protein bound chromophore is the basis of light sensing of many photoreceptors. We tracked Z-to-E photoisomerization of Cph1 phytochrome chromophore PCB in the Pr form in real-time. Two different phycocyanobilin (PCB) ground state geometries with different ring D orientations have been identified. The pre-twisted and hydrogen bonded PCB(a) geometry exhibits a time consta...

We report a computational study of the photo-orientation kinetics in a viscous solution of azobenzene in ethylene glycol, under irradiation with linearly polarized light. The development of anisotropy and its interplay with photoisomerization are simulated by a stochastic model. A distinctive feature of the model is that it takes into account the photo-orientation angular distributions, specifi...
