“…In recent years, our research group has reported a series of novel photosensitive micellar solutions, such as the single‐chain polymerizable surfactant n‐cetyl dimethylallyl ammonium chloride (CDAAC)/ trans‐ ACA (Chen, Fang, Jin, et al, 2016; Chen, Fang, Yu, et al, 2016), Gemini surfactant propylene‐(dimethyldioctadecylammonium chloride) (18‐3‐18)/ trans‐ ACA (Yu et al, 2015), and Gemini surfactant N, N′‐bis (octadecyl dimethyl)‐1, 2‐dichloride‐propyl ammonium salt (C18‐3‐C18)/ trans‐ OMCA (Liu et al, 2018). Furthermore, we have established the rheo‐kinetic equation systematically for the first time to describe the dynamic changes of rheological properties during UV irradiation (Chen, Fang, Jin, et al, 2016; Chen, Fang, Yu, et al, 2016; Fang et al, 2015; Yang et al, 2016), However, there have been no reports about photoresponsivity viscoelastic micellar solutions containing trimeric cationic surfactants.…”

Photosensitive micellar solutions of mixed surfactants and photosensitive additives have gained much interest. However, there are no reports on photosensitive micellar solutions containing trimeric cationic surfactant. In the study, novel photosensitive viscoelastic micellar solutions consisting of trimeric cationic surfactant (TEC) and trans‐ortho‐methoxycinnamic acid (trans‐OMCA) were investigated. This study utilized rheology, UV–vis spectroscopy, and cryo‐TEM to investigate the photo‐responsive behavior and mechanism of the TEC/trans‐OMCA micellar solutions. Rheological studies revealed that the concentration of TEC and trans‐OMCA, as well as temperature, significantly affected the viscoelastic properties of the micellar solutions. Furthermore, the Carreau and Maxwell models might be used to characterize the flow curves and viscoelasticity of the micellar solutions, respectively. Notably, TEC/trans‐OMCA micellar solutions exhibited excellent light‐induced thinning characteristic, with the optimal performance at a mass ratio of φ = 0.5. After UV irradiation, the zero‐shear viscosity of TEC/trans‐OMCA (0.6/0.3 wt%) micellar solution was reduced by 352 times, while the viscoelasticity and the area of hysteresis loops were significantly reduced. This drastic change in the rheological characteristics of the micellar solutions could be attributed to the photoisomerization of trans‐OMCA and the resulting changes in the internal microstructure of the solutions. Moreover, the viscosity of the micellar solutions diminished as the temperature increased, with the remaining viscosity of the TEC/trans‐OMCA (1.0/0.5 wt%) micellar solution at 36.4 mPa s at 95°C. This study expands on the potential utilization of oligomeric surfactants in the construction of photorheological viscoelastic fluids.

“…Undoubtedly, the fast response or slow response of photosensitive materials plays an important role in determining its practical application in fields such as targeted drug release or sunscreen in personal care. There are only a few studies − concerning the photoisomerization kinetics of photosensitive molecules. Hence, the effect of the photosensitive aromatic salt structure on the fabrication and property of surfactant aggregates is worth studying.…”

Mixed systems of the Gemini cationic surfactant trimethylene-1,3-bis (dodecyldimethylammonium bromide) (12-3-12·2Br–) and the photosensitive additives trans-methoxy sodium cinnamates with different substituent positions (trans-ortho-methoxy cinnamate, trans-OMCA; trans-meta-methoxy cinnamate, trans-MMCA; and trans-para-methoxy cinnamate, trans-PMCA) were selected for investigating the effects of the substituting position of methoxy on the system phase diagram and UV light-responsive behavior of the wormlike micelles. The differences in phase behaviors of the selected systems were analyzed by calculating the potential distribution, molecular volume, and free energy of solvation of cinnamates and the binding energies between photosensitive additives and the surfactant. The photoresponsive behaviors of wormlike micelle solutions formed in the selected systems were studied by the rheological method and UV–vis and H nuclear magnetic resonance (1H NMR) spectroscopy; the kinetics of photoisomerization of trans-OMCA, trans-MMCA, and trans-PMCA were studied by first-order derivative spectrophotometry. The results reveal that the methoxy substituent position has a great influence on the phase behavior and photosensitivity of the studied systems. In addition, the photoisomerization of the studied cinnamates follows the first-order opposite reaction laws; the different reaction rates play the decisive role in the photosensitivity of the wormlike micelles. This paper would afford a deeper understanding of the UV light-responsive mechanism at the molecular level and provide essential guidance in preparing smart materials with adjustable light sensitivity.
