Han, Yanning; Zhang, Tong; Chen, Xinyu; Chen, Qiao; Hao, Jingjun; Song, Weichao; Zeng, Yongfei; Xue, Pengchong published an article in 2021. The article was titled 《Guest-Regulated Luminescence and Force-Stimuli Response of a Hydrogen-Bonded Organic Framework》, and you may find the article in ACS Applied Materials & Interfaces.SDS of cas: 4316-58-9 The information in the text is summarized as follows:
Guest mols. may endow porous materials with new or enhanced properties as well as functions. Here, a porous hydrogen-bonded organic framework (HOF) constructed from a three-armed triphenylamine derivative is used to investigate how guests regulate photoluminescence and trigger force-stimuli response. It was found that guest solvents in pores might regulate HOF′s luminescence. Interestingly, acetic acid as a guest endowed HOF materials with longer emission wavelengths and triggered the responses to mech. force stimuli. Under shear force, an obvious blueshift in emission spectra was observed because of the loss of free guests and the conversion of π-stacking model. Further blue-shifted emission appeared while the bound guests were completely removed by heating. Mechanofluorochromic HOF materials could be regenerated through recrystallization and adsorbing guest. Conversely, HOFs with other guests and activated HOFs only resulted in a slight change in their fluorescence behaviors after force stimuli. The results came from multiple reactions, including the reaction of Tris(4-bromophenyl)amine(cas: 4316-58-9SDS of cas: 4316-58-9)
In other references, Tris(4-bromophenyl)amine(cas: 4316-58-9) is often used in the synthesis of porous luminescent covalent–organic polymers (COPs)SDS of cas: 4316-58-9
