Developing new Schiff base molecules for selective colorimetric sensing of Fe3+ and Cu2+ metal ions: Substituent dependent selectivity and colour change
Abstract New Schiff base chemosensors (1–5) based on aryl ether amine were synthesized and explored the colorimetric sensing of metal ions. A highly selective colorimetric sensing of Fe3+ ions wasExpand
Bay Functionalized Perylenediimide with Pyridine Positional Isomers: NIR Absorption and Selective Colorimetric/Fluorescent Sensing of Fe3+ and Al3+ Ions
TLDR
The mechanistic studies indicate that Lewis acidic character of Fe3+ and Al3+ ions were responsible for selective color change and fluorescence quenching of HMP-PDI dyes in DMF. Expand
Triphenylamine based reactive coloro/fluorimetric chemosensors: Structural isomerism and solvent dependent sensitivity and selectivity.
TLDR
Reactive chemosensors, ortho and para-CPDP, exhibited selective and distinguishable colorimetric sensing of Fe3+ and Al3+ ions and isomerism and solvent dependent fluorescence sensing of Zn2+. Expand
Synthesis of new colori/fluorimetric chemosensor for selective sensing of biologically important Fe³⁺, Cu²⁺ and Zn²⁺ metal ions.
New Schiff base chemosensors (1 and 2) based on aryl ether amine were synthesized and demonstrated positional isomer and functional group dependent colori/fluorimetric sensing of Fe(3+), Cu(2+) andExpand
Synthesis of tunable, red fluorescent aggregation-enhanced emissive organic fluorophores: stimuli-responsive high contrast off–on fluorescence switching
Triphenylamine (TPA) and N-methylbarbituric acid/indanedione-based donor–acceptor derivatives were synthesized and demonstrated molecular conformation and packing dependent tunable fluorescence fromExpand
Drastic Modulation of Stimuli-Responsive Fluorescence by a Subtle Structural Change of Organic Fluorophore and Polymorphism Controlled Mechanofluorochromism
Stimuli-responsive fluorescence modulation of organic fluorophores is closely related to their structural organization, noncovalent interactions, ability to adopt different conformation, and phaseExpand
Aggregation Induced Emission of Excited-State Intramolecular Proton Transfer Compounds: Nanofabrication Mediated White Light Emitting Nanoparticles
Excited-state intramolecular proton transfer (ESIPT) compounds, 2-(2-((2-hydroxybenzylidine)amino)phenoxy)benzonitrile (1) and 2-(4-((2-hydroxy-4-methoxybenzylidine)amino)phenoxy)benzonitrile (2)Expand
Self-reversible thermofluorochromism of D–A–D triphenylamine derivatives and the effect of molecular conformation and packing
Triphenylamine (TPA) based donor–acceptor–donor (D–A–D) compounds were synthesized showing aggregation enhanced emission (AEE) and molecular conformation and packing dependent rare self-reversibleExpand
A crab claw shaped molecular receptor for selective recognition of picric acid: supramolecular self-assembly mediated aggregation induced emission and color change
2,6-Pyridine bis(iminoantipyrine) (PyBAP), a crab claw shaped open neutral molecular receptor with multiple non-covalent sites, showed selective recognition of picric acid (PA) through supramolecularExpand
