Structure and Spectroscopic Characterisation of Phenanthroline‐Based Iodobismuthate(III) Complexes Utilised for Raw Acoustic Signal Classification

Advanced Intelligent Discovery, EarlyView.
Memristors based on trimethylsulfonium (phenanthroline)tetraiodobismuthate have been utilised as a nonlinear node in a delayed feedback reservoir. This system allowed an efficient classification of acoustic signals, namely differentiation of vocalisation of the brushtail possum (Trichosurus vulpecula).

L-Aspartic acid pyridinium salts: In silico, synthesis and adjuvant vs antibiotic antibacterial evaluation

Results in Chemistry
In the present study, a new series of chiral L-aspartic acid pyridinium salts have been designed, guided by molecular docking as antiemetics via TrySR or DNA GryB inhibitors, as well as an adjuvant to chloramphenicol via CAT-III inhibitor to continue ...

Synthesis of Pyridinium Moiety Containing Triazolyl Purines

Molbank
Pyridinium salts of 2-piperidinyl-6-triazolylpurine derivatives were obtained by the introduction of pyridinium moieties into the propane-1,3-diol fragment at the N(9) position of purine to enhance the solubility of 2-amino-6-triazolylpurine derivatives ...

A Simple and Efficient Approach to the Synthesis of Endo and Exo Bicyclo[6.1.0]nona-3,5-diene-9-carboxaldehyde

Molecules, 2007
Monobromination of 1,5-cyclooctadiene, followed by cyclopropanation with ethyl diazoacetate, led to the formation of endo and exo ethyl 4,5-dibromobicyclo[6.1.0]nonane-9-carboxylates 3a and 3b. Bis-dehydrobromination of 3a and 3b using 1,8-diazabicyclo[5,

Selective detection of fluoride based on a pyridinium n-phenolate-calix[4]pyrrole displacement assay: an undergraduate laboratory experiment

Química Nova, 2014
A two-step experiment is proposed for a third year class in experimental organic chemistry. Over a period of five weeks, the students synthesized calix[4]pyrrole, a receptor that is highly selective for fluoride, and a pyridinium N-phenolate dye ...
