Light-Induced Tunable Thermoresponsive Behaviors of Polymeric Photoswitches Bearing Benzylidene Oxazolone Pendant Groups |
| 초록 |
New thermo- and photoresponsive random copolymers, poly(3-vinylbenzylidene oxazolones-co-dimethylacrylamide) (PVBO-co-PDMA), with different incorporation ratios of benzylidene oxazolone (VBO) units were synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization followed by post modification with hippuric acid to investigate the light controlled thermal phase transition behaviors. UV-Vis absorption measurements were employed to study the efficiency of photoisomerization of the benzylidene oxazolone moieties upon irradiation with UV and Visible light (365 nm and 650 nm) for various time intervals. Temperature-dependent optical transmission studies (turbidimetry) were also carried out on the aqueous solutions to investigate how the lower critical solution temperature (LCST) values were influenced by photoirradiation. |
