Researchers develop hierarchically self-assembled homochiral helical microtoroids NatureNano
Typically, 1.75 mg BU was dispersed into 0.5 ml MeOH in a 3 ml sample vial or cuvette. The mixture was heated at 343 K until the solid was entirely dissolved. The solution was cooled from 343 K to 293 K at a speed of 5 K minwith a UH4150 variable-temperature accessory. A drop of the cooled solution was then transferred to the target substrate via a syringe. After natural evaporation at room temperature , interfacial assemblies were obtained and used for further measurements.
To avoid scattering effects originating from the large size of these microstructures, the solid samples were removed from the substrates with a scraper and were transferred to a BaSOsample plate, which was then measured through the UV–vis diffuse-reflectance spectrum mode on a UV-2600 spectrophotometer.The fluorescence spectra were recorded on an F-4500 fluorescence spectrophotometer at a voltage of 400 V with a 5 nm slit for both excitation and emission sides.
