The intermol. interactions and mol. packing form of fluorescent mols. have a huge impact on their optical properties, especially for AIE mols. As a class of typical AIE mols., tetraphenylethene (TPE) and its derivatives have prominent optical properties; nevertheless, separation of mixtures of E/Z isomers is a great challenge. Herein, a series of aromatic-substituted TPE derivatives were synthesized and used to sep. mixtures of E/Z isomers by common column chromatog. with high yields, as confirmed by single crystal anal., mass spectrometry and NMR spectroscopy. The structure-property relationships of these mols. were systematically investigated by a combination of spectroscopic methods, theor. calculations and single crystal data anal. E/Z isomers exhibit many different fluorescent properties, such as AIE and mechanochromic behavior. Moreover, the position of N on the substituted pyridine ring also has an effect on the mol. stack pattern and the fluorescent properties. Collectively, our findings could not only improve the fundamental understanding of the cis/trans isomerization and photophys. properties of TPE derivatives but also provide a good strategy for designing different substituted groups that can produce various functions and have more potential applications.

2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8) belongs to pyridine. Pyridines, quinolines, and isoquinolines have found a function in almost all aspects of organic chemistry. Pyridine has found use as a solvent, base, ligand, functional group, and molecular scaffold. As structural elements, these moieties are potent electron-deficient groups, metal-directing functionalities, fluorophores, and medicinally important pharmacophores.
