A novel on/off fluorescent rhodamine-based hexapodal Fe(3+) probe (L) containing a cyclotriphosphazene core was synthesized by an azide-alkyne "click-reaction". The compounds (1-5 and L) were characterized FT-IR; (1)H, (13)C, (31)P NMR; MALDI MS spectrometry. optical sensor features for the complex of L investigated UV-vis fluorescence spectroscopy. stoichiometry L-Fe(3+) found to be 1:3 (ligand/metal ion), detection limit determined as 4.8 μM (0.27 mg L(-1)) ions. reusability tested...
The main aim of this paper is to describe the separation and properties four possible structural isomers non-peripherally substituted nickel(II) phthalocyanine. Two (C4h D2h) compound were separated by preparative thin layer chromatography; however other two (C2v Cs) HPLC only with an analytical chiral column. individual symmetry assigned on basis 1H NMR signals aromatic protons phthalocyanine ring system. pure C4h isomer exhibited liquid crystalline at room temperature while isomeric...
The reactions of hexachlorocyclotriphosphazatriene, N3P3Cl6, with N/O-donor-type N-alkyl (or aryl)-o-hydroxybenzylamines (1a−1e) produce mono- (2a−2e), di- (3a−3d), and tri- (4a 4b) spirocyclic phosphazenes. tetrapyrrolidino monospirocyclic phosphazenes (2f−2i) are prepared from the partly substituted compounds (2a−2d) excess pyrrolidine. dispirodipyrrolidinophosphazenes (3e−3h) trispirophosphazenes (3i−3k) obtained trans-dispirophosphazenes pyrrolidine sodium (3-amino-1-propanoxide),...
There is still room for improvement in supramolecular systems based on cyclophosphazene derivatives and their potential applications.
A systematic series of fluorescence chemosensors based on cyclotriphosphazene derivatives were designed, synthesized, and evaluated for their sensing behaviors toward metal ions.
Two constitutionally isomeric bis-pyrenyl phenol dendrons (<bold>4</bold>and<bold>6</bold>) and their dendrimer-like cyclotriphosphazene derivatives (<bold>5</bold>and<bold>7</bold>) are designed, synthesized fluorescence detection behaviors evaluated for nitro aromatic compounds (NACs).
We present a comprehensive work and discuss the fluoroprobe properties of synthesized compounds for copper ion detection with stereochemical approach using X-ray crystallographic analysis results.
A cathode material based on polyphosphazene with pyrene-4,5,9,10-tetraone (PTO) units as electroactive groups a high specific capacity in the side chain, poly[(bis(2-amino-4,5,9,10-pyrenetetraone)]phosphazene (PPAPT), is synthesized. The structural characterization of PPAPT carried out by using appropriate standard spectroscopic methods such 31P NMR spectroscopy, FT-IR, DSC, and TGA. found to be an insoluble halogen-free flame retardant accordance results simple test solubility control...
A problem has arisen in using chiral shift reagents (CSR) and solvating agents (CSA) to determine meso racemic forms of diastereoisomers which the stereogenic centers molecules are separated by achiral spacers. It is found that NMR signals both may exhibit doubling on addition CSR/CSA, means unequivocal assignments cannot be made without characterizing effects for separate forms; this particularly important additions CSR/CSA at relatively low concentrations, always result splitting some...
