Anion-directed structural tuning of two azomethine-derived Zn complexes with optoelectronic recognition of Cu in aqueous medium with anti-cancer activities: from micromolar to femtomolar sensitivity with DFT revelation.

Herein, two novel mononuclear transition metal Zn complexes [Zn(HL)(N)(OAc)] (NS-1) & [Zn(HL)(ClO)] (NS-2) have been synthesised using a tridentate clickable Schiff base ligand, HL (2-methyl-2-((pyridin-2-ylmethyl)amino)propan-1-ol), and the polyatomic monoanions N and ClO for NS-1 and NS-2 respectively. Interestingly, NS-1 and NS-2 have been explored for the detection of Cu with an LOD of 48.6 fM (response time ∼6 s) and 2.

Electrochemical Nanosensors for Sensitization of Sweat Metabolites: From Concept Mapping to Personalized Health Monitoring.

Sweat contains a broad range of important biomarkers, which may be beneficial for acquiring non-invasive biochemical information on human health status. Therefore, highly selective and sensitive electrochemical nanosensors for the non-invasive detection of sweat metabolites have turned into a flourishing contender in the frontier of disease diagnosis. A large surface area, excellent electrocatalytic behavior and conductive properties make nanomaterials promising sensor materials for target-specific detection.

Regioselective synthetic approach for key precursors of 6-arylbenzo[]phenanthridin-10-ol derivatives: a useful compound for selective chromogenic recognition of fluoride.

A regioselective synthetic strategy for 6-aryl-8,9-dihydrobenzo[]phenanthridine-10(7)-ones (4) is accomplished using a one-pot four-component reaction by fine-tuning the reaction temperature. DMSO is excellently used as a reactant-cum-solvent to introduce a carbonyl functionality regioselectively at the C-10 position of the benzophenanthridine backbone, an MCR, which is unknown yet. The elegant features of this strategy are the formation of two CC, one CN, and one CO bonds in a single step, without using a base and an activator for the oxygenation process.

Selective recognition of ammonia and aliphatic amines by C-N fused phenazine derivative: A hydrogel based smartphone assisted 'opto-electronic nose' for food spoilage evaluation with potent anti-counterfeiting activity and a potential prostate cancer biomarker sensor.

In real day scenario, it is an urge to provide a single solution of multiple problems. In this regard, herein rapid, selective and highly efficient chromo-fluorogenic detection of ammonia/aliphatic amines over aromatic amines has been investigated by means of a novel "opto-electronic nose", CN-2, synthesized in a single-step via multiple inter/intramolecular C-N fusion reactions. The in-situ generated mono-protonated CN-2 can selectively detect primary to secondary to even tertiary aliphatic amines over aromatic amines within ∼40 S with extremely low detection threshold values of 27.

Knoevenagel condensation triggered synthesis of dual-channel oxene based chemosensor: Discriminative spectrophotometric recognition of F, CN and HSO with breast cancer cell imaging, real sample analysis and molecular keypad lock applications.

A novel oxene based unusual sensory receptor (HyMa) has been synthesized via.Knoevenagel condensation triggered carbon-heteroatom (oxygen) intramolecular bond formation reaction at room temperature for discriminative detection of multi-analytes like HSO, CN & F by spectro-photometric alterations with profound selectivity with the detection limit of 38 ppb, 18 ppb & 94 ppb respectively. Examination of the sensing mechanism was exhaustively investigated through several spectroscopic means like H NMR, FT-IR, absorption and fluorescence spectra etc.

Trace-Level Humidity Sensing from Commercial Organic Solvents and Food Products by an AIE/ESIPT-Triggered Piezochromic Luminogen and ppb-Level "OFF-ON-OFF" Sensing of Cu: A Combined Experimental and Theoretical Outcome.

Selective and sensitive moisture sensors have attracted immense attention due to their ability to monitor the humidity content in industrial solvents, food products, ., for regulating industrial safety management. Herein, a hydroxy naphthaldehyde-based piezochromic luminogen, namely, 1-{[(2-hydroxyphenyl)imino]methyl}naphthalen-2-ol (), has been synthesized and its photophysical and molecular sensing properties have been investigated by means of various spectroscopic tools.

Selective Identification and Encapsulation of Biohazardous -Xylene among a Pool of Its Other Constitutional C Alkyl Isomers by Luminescent d MOFs: A Combined Theoretical and Experimental Study.

Separation of C alkyl-aromatics (-xylene, -xylene, and -xylene) remains one of the most challenging tasks to date due to their similar physical and chemical properties. Cd- and Zn-based luminescent metal-organic frameworks (MOFs) have been synthesized for the selective identification of -xylene in a pool of other isomers by fluorometric methods. Inhibition of the photoinduced electron transfer process is the prime reason for fluorescence enhancement, owing to the comparable molecular orbital energies for -xylene in comparison with - and -xylene.
