Two anthracene derivatives appended on cyclen (1,4,7,10-tetraazacyclododecane) moieties were synthesized and characterized. In these new compounds, the anthryl is used as a substitute for the nucleobases of classical PNA backbone, and the cyclen moiety appends on the terminal amino group. The interaction of the compounds with DNA was systematically investigated by absorption, fluorescence, and ...

A novel iridium(III) complex-based chemosensor bearing the 5,6-bis(salicylideneimino)-1,10-phenanthroline ligand receptor was developed, which exhibited a highly sensitive and selective color change from colorless to yellow and a visible turn-off luminescence response upon the addition of Cu(II) ions. The interactions of this iridium(III) complex with Cu2+ ions and thirteen other cations have b...

Spectral data during a chelatometric titration were utilized for determining an equivalence point of the titration. Three-dimensional titration data were analyzed by fitting to a theoretical equation that was derived from equilibrium equations among a metal ion, an indicator and EDTA. The equation with optimized parameters successfully explained the three-dimensional titration data. This method...

A new BODIPY-azaindole based fluorescent sensor 1 was designed and synthesized as a new colorimetric and ratiometric fluorescent chemosensor for fluoride. The binding and sensing abilities of sensor 1 towards various anions were studied by absorption, emission and (1)H NMR titration spectroscopies. The spectral responses of 1 to fluoride in acetonitrile-water were studied: an approximately 69 n...

A simple, sensitive, rapid, reproducible, economical and easily accessible method for the determination of tinidazole tablets is described. From the experiment carried out there is the need for recrystallisation of tinidazole tablet before it is analysized. Ultraviolet (UV) absorption analysis corresponds to the result obtained with non-aqueous titration. And the best solvent to be use for non-...

The interaction of the dye reactive bright red 6C with bovine serum albumin has been investigated. Formation of a complex between reactive bright red 6C and bovine serum albumin was detected by use of absorption difference spectroscopy. The curves obtained by titration of the protein against the dye were recorded at different pH and ionic strength of the solution. An unusual form of titration c...
