1-Alkylisatins via Aldol-Retro-Aldol Condensation.
Drastic Modulation of Stimuli-Responsive Fluorescence by a Subtle Structural Change of Organic Fluorophore and Polymorphism Controlled Mechanofluorochromism
Aggregation enhanced emissive fluorophores are synthesized and molecular structure controlled tunable fluorescence was demonstrated and hard crushed −2b polymorph showed two different mechanofluorochromism (MFC) when heated at 80 and 180 °C as well as topochemical conversion from 2b to 2a.
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-reversible…
Synthesis of new colori/fluorimetric chemosensor for selective sensing of biologically important Fe³⁺, Cu²⁺ and Zn²⁺ metal ions.

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.
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)…
