Azobenzene-based polycatenars: Investigation on photo switching properties and optical storage devices

Transition from lamellar to nanostructure mesophases in azobenzene-based hockey-stick polycatenars

“…This confirms a reversible transformation to the trans isomer again, which means that the trans – cis photoisomerization is a reversible process. 70 To investigate the effect of the alkyl chain length on the photoisomerization, compound B10/22 with longer chains at both ends of the aromatic core compared to B6/16 was also investigated in a similar manner (Fig. S21, ESI†).…”

Photo-driven electron transfer from FAPbBr3 perovskites nanocrystals to photodeactivatable 4-(phenylazo) benzoic acid

“…20,21 Different types of molecular switches, including stilbenes, 22 diarylethenes, 23 spiropyrans 24 and azobenzene, 25 are important for fabricating reversible photoresponsive systems. Azobenzene derivatives among these molecular switches have been extensively studied, 26 and found applications for data storage 27 as well as liquid crystals 28 and optical switches. 29 Azobenzene derivatives consist of two phenyl rings attached through an azo group, which possess unique and predominant photo-reversible properties.…”

β-Cyclodextrin/Azobenzene Microspheres Loaded with Paraquat Are Safe and Effective

“…The azobenzene moiety is a common β-CD guest. As shown in Figure , UV irradiation can induce reversible trans-to-cis isomerization of azobenzene, resulting in two forms of azobenzene: trans-azobenzene and cis-azobenzene. β-CDs can incorporate the trans-azobenzene group into the cavities via host–guest complexation but cannot incorporate the cis-azobenzene group into cavities due to size mismatch. , As a result, we decided to develop a PQ-based, photoresponsive polymeric formulation for the controlled release of PQ with low toxicity to humans.…”
