Dehydrative Substitution Reaction in Water for the Preparation of Unsymmetrically Substituted Triarylmethanes: Synthesis, Aggregation‐Enhanced Emission, and Mechanofluorochromism

Abstract Water as a reaction media in chemical transformations has several advantages in terms of safety and non‐toxicity. However, dehydrative substitution reaction in water is a highly challenging operation. In this paper, we have reported a sulfamic acid‐mediated dehydrative substitution reaction of benzofuryl alcohols with several nucleophiles in water towards the scalable, easily isolable, synthesis of unsymmetrically substituted triarylmethanes (TRAMs) in good to excellent yields (up to 92 %). Moreover, we have demonstrated that rationally designed propellor‐shaped triarylmethanes promote aggregation‐induced emission (AIE) through restricted intramolecular rotation with irreversible mechanoflurochromic property.

Troger's Base Derived Butterfly Shaped Contorted AIEgens for Dead Bacterial Cell‐Imaging

Abstract This work describes the design and synthesis of contorted dual emissive luminogen based on Tröger's base scaffold. The underlying principle of our design strategy was to use Tröger's base as the core scaffold and functionalize appropriately to avoid the detrimental π‐π stacking responsible for the emission quenching and induce RIR in the aggregated state and thereafter investigate their photophysical, electrochemical, and thermal properties. The unique white light emission of the fluorophores in the solid‐state together with excellent biocompatibility, photo, and thermal stabilities provided an opportunity for the application of one of the molecules for bacterial cell imaging. The luminogen was biocompatible and surprisingly possess an ability to selectively stain the dead bacterial cell debris, a unique property that can be exploited for the confirmation of cell lysis.
