Halogen-substituent effect on the spectroscopic properties of 2-phenyl-6-dimethylaminobenzothiazoles

Anthracene–naphthylacetonitrile fluorescent isomers and Cl/H substituent dependent molecular packing, solid-state fluorescence and mechanofluorochromism

“…The integration of Cl disrupted slipped π-stacking but heavy atom halogen substitution reduced the fluorescence efficiency as well as blue shifted the fluorescence. [55][56][57] Density functional theoretical (DFT) studies were performed to gain insight into the electron density distribution and charge transfer (Fig. 3b).…”
