TLDR
A photoresponsive orthogonal supramolecular system is developed by combining the UV-light-responsive Azo/α-CD and green- light-responsive ipAzo/γ-CD host-guest complexes, which forms a strong host-Guest complex with γ-cyclo dextrin whereas trans-ipAzo binds weakly.Abstract:
We synthesized a novel green-light-responsive tetra-ortho-isopropoxy-substituted azobenzene (ipAzo). Cis-ipAzo forms a strong host-guest complex with γ-cyclo dextrin (γ-CD) whereas trans-ipAzo binds weakly. This new photoresponsive host-guest interaction is reverse to the well-known azobenzene (Azo)/α-cyclodextrin (α-CD) complex, which is strong only between trans-Azo and α-CD. By combining the UV-light-responsive Azo/α-CD and green-light-responsive ipAzo/γ-CD host-guest complexes, a photoresponsive orthogonal supramolecular system is developed.read more

Light‐Responsive Serinol‐Based Polyurethane Nanocarrier for Controlled Drug Release
TL;DR: A new and facile strategy for the synthesis of light-responsive polyurethanes (LrPUs) based on serinol with o-nitrobenzyl pendent groups is developed, which can be easily applied to the straightforward synthesis of various new ser inol-based monomers with different stimuli-responsive properties and therefore expand the family of biodegradable polymers.
