New salicylaldehyde azine esters: Structural, aggregation induced fluorescence, electrochemical and theoretical studies

Experimental and molecular dynamics studies on aggregation behaviour of salicylaldehyde azine ester

“…18 A systematic theoretical analysis in combination with experimental evidence of the aggregation of salicyaldehyde azine derivatives using an explicit water model is not reported to a Department of Chemistry, Manipal Institute of Technology, Manipal Academy of the best of our knowledge. In the present study, an in-depth understanding of the aggregation phenomenon exhibited by a salicylaldehyde azine ester (SAE) reported by our group 19 is showcased through both experimental and theoretical investigations. SAE is an unsymmetrical ester with two phenyl rings of which one carries a free ortho-hydroxyl functional group as depicted in Fig.…”

“…SAE (CHN) anal. for C 18 H 18 N 2 O 4 ; % found (calculated): C, 66.12 (66.25); H, 5.55 (5.52); N, 8.38 (8.59) was synthesized as per the earlier report 19 and used for all the experiments mentioned in this study.…”

Aggregation-induced emission-active azines for chemosensing applications: a five-year update

“…In another work, Tharmalingam et al developed an AIE-ESIPT active star-shaped azine-based Cu 2+ sensor (11) from a triaminoguanidine precursor [Fig. 3H and Table 1, entry 3].…”

“…8 AIEgens display multiple advantages compared to traditional ACQ molecules in their high fluorescence quantum yield in aggregated states and at higher concentrations, significant Stokes shift, and low cytotoxicity. AIE-active azine molecules have paved the way for innovative technologies in diverse areas including chemosensing, 3 organic electronic devices, 9 nanomaterials, 10 electro-optical devices, 11 organic functional materials, 12 battery materials, 13 COFs, 14 imaging studies, 15,16 drug delivery, 17 supramolecular chemistry, 18 light-harvesting systems, 19 etc. Over the years, there have been many milestone developments in the field of AIE-active azine-based chemosensors (Scheme 1).…”

Synthesis of Symmetrical Acetophenone Azine Derivatives as Colorimetric and Fluorescent Cyanide Chemosensors

“…For example, Azine derivatives bearing hydroxyl group have been used as colorimetric and fluorescent chemosensors [1,5,[11][12][13]. Most azine chemosensors were produced from aryl benzaldehydes and hydrazine hydrates as starting materials under reflux condition [14][15][16]. This paper reports the synthesis of symmetrical azine 1 and 2 from acetophenone derivatives and hydrazine hydrate (Scheme 1).…”
