研究目的
Investigating the green-light-induced melting of self-assembled azobenzene nano/microstructures and their application in creating fluorescent organic materials.
研究成果
The study successfully demonstrated green-light-induced melting of self-assembled azobenzene structures, leading to color tuning and fluorescence switching. Phase separation in binary mixtures was key to retaining fluorescence functions, offering potential applications in biological sensors, switches, and optical devices.
研究不足
The study is limited by the specific molecular structures used and the conditions under which the experiments were conducted. Further optimization could explore a wider range of molecular designs and environmental conditions.
1：Experimental Design and Method Selection:
The study involved the formation of fluorescent aggregates from trigonal molecules with ortho-dialkylated azobenzene wings and their exposure to green light to observe color tuning and fluorescence switching.
2：Sample Selection and Data Sources:
Samples included 3BuES and 3BuAz molecules, with data collected through SEM, OM, and FOM.
3：List of Experimental Equipment and Materials:
Spectroscopic-grade THF, Milli-Q water, Shimadzu UV-2600 UV-vis spectrophotometer, Horiba FluoroMax-4 spectrofluorometer, Tokina Supercure-204S light source, Hitachi E-1030 ion sputter, TESKAN-MIRA3-LM microscope, Olympus BX53 microscope.
4：Experimental Procedures and Operational Workflow:
Self-assembled structures were created by adding water to THF solutions of the molecules, followed by exposure to green light and observation under various microscopes.
5：Data Analysis Methods:
UV-vis absorption and fluorescence spectra were analyzed to understand the light-induced changes in the molecular structures.
