Bis(pyridyl)-disulfonamides: structural comparison with their carboxamidic analogues and the effect of molecular geometry and supramolecular assembly on their photophysical properties

Autor: Moyna Das, Datta Markad, Suvendu Maity, Prasanta Ghosh, Madhushree Sarkar

Publikováno v: New Journal of Chemistry. 46:7374-7384

Presence of Sulphur or Carbon atom in amidic group is reciprocated in their solid state structures. AIE or ACQ of disulphonamides is explained on the basis of their crystal packing.

Controlling light emitting properties in bis(pyrenyl)-di-imines by tuning the chemical functionality of the spacer group

Autor: Madhushree Sarkar, Moyna Das, Prasanta Ghosh, Suvendu Maity, Vishakha Jaswal

Publikováno v: Molecular Systems Design & Engineering. 6:1047-1055

Aggregation-caused quenching (ACQ) and aggregation-induced emission (AIE) are dictated by the molecular aggregation which in turn is decided by the chemical features present in a molecule. The photophysical properties of bis(pyrenyl)-di-imines were i

Photophysical properties of di-Schiff bases: evaluating the synergistic effect of non-covalent interactions and alkyl spacers in enhanced emissions of solids

Autor: Madhushree Sarkar, Moyna Das, Fayaz Baig

Publikováno v: RSC Advances. 6:57780-57792

Photophysical properties of di-Schiff base compounds in the solution and solid states are explored. The di-Schiff bases with alkyl spacers (ethyl, butyl and hexyl) showed enhanced light emitting properties in the solid state, while quenching was obse
