- Self-assembly of a benzothiazolone conjugate into panchromatic fluorescent fibres and their application in cellular imaging
-
We report the synthesis and characterization of the structures formed by self-assembly of 4-chloro-2(3H)-benzothiazolone (CBT) into panchromatic fibres and their application in cellular imaging. The aggregation properties of the synthesized compound were studied extensively under different solvents and concentrations and their morphologies examined at a supramolecular level by various microscopic techniques such as atomic force microscopy (AFM), fluorescence microscopy, and optical microscopy. Interestingly, the self-assembled structures formed byCBTreveal panchromatic emission properties and show blue, green, and red fluorescence under different excitation wavelengths. The mechanism of structure formation of the self-assemblies was studied through different techniques such as concentration-dependent1H-NMR, ATR-FTIR, UV-visible spectroscopy, and fluorescence spectroscopy. Finally, the utility ofCBTfor cell imaging applications was demonstrated and it can be noted thatCBTwas efficiently taken up by mammalian cells and the cells revealed panchromatic emission in the blue, green, and red channels. The intensities of the fluorescence observed were blue > green > red and the dye interestingly does not exhibit any fluorescence quenching.

- CuI-catalyzed one-pot synthesis of benzothiazolones from 2-iodoanilines-derived carbamates and sodium sulfide
-
A copper-catalyzed procedure was developed for assembling benzothiazolones from ethyl 2-iodophenylcarbamates and sodium sulfide. A number of functional groups, such as methoxy, acyl, amide, carboxylate, trifluoromethyl, fluoro, and chloro, were tolerated under these conditions, providing benzothiazolones in good yields.
