Superamphiphiles are considered as a promising approach for fabricating stimuli-responsive materials. Sensitivity to more than one stimulus can improve the system's versatile performance. In this study, we proposed a facile dual-responsive vesicle constructed from Bola-type superamphiphiles. An azobenzene dimer linked by a disulfide bond was synthesized. As the guest molecule, the azobenzene dimer

Light modulation of the isomerization and aggregationbehavior of ionic liquids in aqueoussolution is of great importance from a fundamental and technical point of view. In this work, 4 kinds of azobenzene-based photoresponsive ionic liquids 2-hydroxyethyl-dimethyl-[10-(4-phenylazo-phenoxy)-decyl]-ammonium bromide (ChoC10Azo), 2-hydroxyethyl-dimethyl-[6-(4-phenylazo-phenoxy)-hexyl]-ammonium bromide

The end-to-end assembly and disassembly of gold nanorods were realized via HS-β-CD recognition and controllable by both UV light irradiation and guest competition.
A gated synthetic ion channel with beta-cyclodextrin as the pore and azobenzene as the gate is reported. Irradiation converts a tethered trans-azobenzene to cis-azobenzene which likely transforms the channel from a self-inclusion complex to a dissociated structure. This transformation results in an increase in anion transport and a decrease in cation transport across a phospholipid vesicle membrane.

stable photostationary state monitored by UV/Vis absorption spectroscopy and 1H NMR spectra. These results indicate that 19 can act as an efficient photo-responsible probe to remote control AChE activity. Molecularmodelling analysis of 19 Z revealed its affinity by the peripheral anionic site of AChE, providing understanding of its higher inhibition power. This study contributes to the development of new
