UV and NIR dual-responsive self-assembly systems based on a novel coumarin derivative surfactant

Abstract

Controllable self-assembly systems have attracted increasing attentions in both academic and industrial fields recently. Herein, we designed and synthesized a new photo-degradable anionic surfactant (PAS) with coumarin group which could be degraded by both UV and NIR lights. Thus, its micelles that formed by sodium salts of PAS (PAS-Na) could be broken controllably under UV or NIR irradiation. Surface tension measurements, DLS and Cryo-TEM were adopted to investigate the formation and disruption of PAS-Na micelles. PAS could also form wormlike micelles and vesicles when they co-assembled with common surfactant tetradecyldimethylamine oxide (C14DMAO). These wormlike micelles and vesicles could be degraded by UV and NIR irradiation due to the participation of PAS. Accordingly, the rheology properties of wormlike micelles and vesicles were also changed significantly. Finally, the stimulus-responsive system was used to control the diffusion of hydrophobic and hydrophilic molecules. And it has shown controllable release effects on both of hydrophobic and hydrophilic molecules.
