Polymerization boosting cascade energy transfer based on opened glucopyranosyl β-cyclodextrin

Abstract: An injectable polysaccharide supramolecular hydrogel was successfully fabricated from opened D-glucopyranosyl β-cyclodextrin with four aldehyde groups (ACD) cross-linked with biomacromolecule chitosan (CS), which was not only benefit to the clustering-triggered...

“…In order to effectively convert light into a substantial amount of heat energy, it is vital to have strong NIR absorption. The GSH-responsive enhancement of absorption at 808 nm makes the transformation of HA@V 2 O 5 NPs to HA@VO x NPs possible to be applied for GSH-activated PTT. To prove this expectation, the GSH-activated photothermal property of HA@V 2 O 5 NPs was primarily assessed.…”

“…Furthermore, the fluorescence lifetime of SC4A/TPA was decreased from 1.40 to 0.62 ns in the presence of energy acceptor DE‐C (Figure S18, Supporting Information), indicating the energy transfer from TPA to the photo‐switch DE‐C in the co‐assembly may go through the Förster mechanism. [ 26 ] On the other hand, the maximum absorption peak of DE‐C is located at 625 nm, thus the closed form of DE can be photo‐isomerized to DE‐O under visible light irradiation (>600 nm), avoiding the excitation of TPA. As shown in Figure 4b, the NIR luminescence of the multivalent assembly was recovered after being irradiated by visible light (>600 nm) for 200 s, which may ascribe to the DE‐C being isomerized to DE‐O, resulting in the energy could not transfer from excited TPA to DE‐O in this system.…”

“…Stimuli-responsive functional materials [1][2][3][4] have received increasing attention due to their indispensable roles in rapid development of science, technology, and artificial intelligence in modern society. However, the dysfunction or loss of function caused by environmental anomalies (e.g., overheating, supercooling, DOI: 10.1002/adom.202301447 over-wetting, over-drying, acid/alkali) greatly hinders their ability to better meet human needs and practical applications.…”
