Inorganic chemistry.Inorg Chem.2016 Oct 11. [Epub ahead of print]
N,N-Dimethylamine and N,N-diphenylamine-decorated highly fluorescent imidazole borates have been synthesized and investigated as new fluorophores for the selective detection of trinitrophenol/picric acid (PA). Structural studies of a probe 1 and PA (1·PA) complex revealed that the adduct formed by

Langmuir : the ACS journal of surfaces and colloids.Langmuir.2016 Oct 10. [Epub ahead of print]
The distribution of ions into a bilayer lipid membrane (BLM) and their adsorption on the BLM are investigated by extracting a hydrophobic cation, rhodamine 6G (R6G+), into a liposome through the dialysis membrane method. R6G+ distribution mainly depends upon the concentration of the coexisting anion

Chemistry (Weinheim an der Bergstrasse, Germany).Chemistry.2016 Oct 6. doi: 10.1002/chem.201603607. [Epub ahead of print]
A novel luminescence microporous lanthanide metal-organic framework (Ln-MOF) based on urea containing ligand was successfully assembled. The structural analyses indicate that the framework exhibited two types of 1D channels and with N-H urea bonds projecting into pores. The luminescence studies reve

Rapid and Precise Coulometric Determination and Separation of Redox Inert Ions Based on Electrolysis for Ion Transfer at the Aqueous Organic Solution Interface

Kihara Sorin,Kasuno Megumi
Analytical sciences : the international journal of the Japan Society for Analytical Chemistry 27(1), 1-11, 2011-01-10
… The coulometric determination can be performed with an efficiency of more than 99% and a precision of better than 0.2% based on the ion transfer under an optimum condition, even if the ion is redox inert such as Na+, K+, Mg2+, Ca2+, ClO4−, picrate or alkylsulfonates. …
