Searching the factual factor in emission tweaking of a reported bisindole based self aggregation sensitive organic emitter: The missing link
Autor: Provakar Paul, Saikat Samanta, Arabinda Mallick, Tapas Majumdar
Publikováno v: Chemical Physics Impact, Vol 8, Iss , Pp 100526- (2024)
A bis-indole derivative, 3,3′-bisindolyl(phenyl)methane (BIPM), is studied by using steady-state and time-resolved optical spectroscopy in several pure and mixed solvents to investigate its solvent sensitive photophysical behavior. The micro-enviro

Disaggregation-induced resurgence of quenched emission of a self-assembled bis-indole system: photophysics, energetics, and dynamics
Autor: Provakar Paul, Saikat Samanta, Arunavo Chatterjee, Arabinda Mallick, Tapas Majumdar
Publikováno v: Physical Chemistry Chemical Physics. 25:10166-10174
A simple, effective, and biologically benign strategy for the disaggregation of 3,3′-bisindolyl(phenyl)methane self-assemblies is presented for emission recovery, where β-CD is employed as the molecular modulator of probe fluorescence.

Controlled tuning of radiative–nonradiative transition via solvent perturbation: Franck–Condon emission vs. aggregation caused quenching
Autor: Provakar Paul, Monaj Karar, Bibhas Mondal, Ujjal Kanti Roy, Ashutosh Ghosh, Tapas Majumdar, Arabinda Mallick
Publikováno v: Physical Chemistry Chemical Physics. 24:18245-18254
The interplay of solvent polarity–proticity guided emission enhancement, and aggregation caused quenching was employed for the fluorescence QY tuning of a synthesized molecule, BIPM, just by adjusting the DiOx–H2O solvent composition.

A New Compound for Sequential Sensing of Picric Acid and Aliphatic Amines: Physicochemical Details and Construction of Molecular Logic Gates
Autor: Arnab Ghosh, Arabinda Mallick, Sourav Kanti Seth, Pradipta Purkayastha, Ashutosh Ghosh, Pradip Pattanayak
Publikováno v: Chemistry – An Asian Journal. 16:1157-1164
Picric acid (PA) at low concentration is a serious water pollutant. Alongside, aliphatic amines (AAs) add to the queue to pollute surface water. Plenty of reports are available to sense PA with an ultralow limit of detection (LOD). However, only a ha
