Discriminative ‘turn-on’ fluorescence sensing of volatile halogenated solvents using a cleft-shaped 4-amino-1,8-naphthalimide Tröger's base fluorophore

Abstract

A cleft-shaped 2-picolyl-4-amino-1,8-naphthalimide Tröger’s base (TBNap) was synthesized and employed as a fluorescent ‘turn-on’ chemosensor for the discriminative sensing of volatile halogenated solvents based on the ICT sensing mechanism. TBNap...

Fluorescent Probes for Detection of Environmental Contaminants (NACs & VOCs): Probe Design from a Supramolecular Perspective

“…[53][54][55] Furthermore, most of the aromatic VOCs, i. e., benzene, toluene, and xylene derivatives, are electron-rich systems and can interact effectively with the electron-deficient fluorescent chemosensors through intermolecular π-π stacking and hydrophobic interactions. [56][57][58] The nature of the electron transfer process predominantly depends upon the band energies of both the fluorophore and sensing analytes which has been discussed in detail afterward. However, their specific recognition is often difficult in some cases, due to the similarity in their interaction patterns.…”

“…We have mostly focused on the recognition of explosives or their simulants NACs in water, where the electron‐deficient nature of these NACs enables them to interact with electron‐rich fluorophores [53–55] . Furthermore, most of the aromatic VOCs, i. e., benzene, toluene, and xylene derivatives, are electron‐rich systems and can interact effectively with the electron‐deficient fluorescent chemosensors through intermolecular π‐π stacking and hydrophobic interactions [56–58] . The nature of the electron transfer process predominantly depends upon the band energies of both the fluorophore and sensing analytes which has been discussed in detail afterward.…”

Tracking the cellular uptake and phototoxicity of Ru(ii)-polypyridyl-1,8-naphthalimide Tröger's base conjugates

“…[3][4][5][6][7][8][9][10][11][12][13] Likewise, Shanmugaraju and co-workers have recently developed several excellent examples of naphthalimide Tro ¨ger's bases and demonstrated their application in a range of supramolecular chemistry applications. [14][15][16][17][18] Ru(II) polypyridyl complexes are known DNA and RNA targeting agents, but a School of Biochemistry and Immunology, Biomedical Sciences Institute, Trinity biological profiling of such complexes has only recently been appreciated and studied in some detail. [19][20][21][22][23][24][25][26][27][28] Hence, the pursuit of Ru(II) polypyridyl complexes as cellular imaging agents and potential theranostics is gathering pace with the recent progression of the thiophane containing TLD1433 to a phase II study for treating non-muscle invasive bladder cancer -the first ruthenium polypridyl based PDT agent to progress to clinical trials.…”
