14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6, belongs to chiral-catalyst compound, is a common compound. In a patnet, once mentioned the new application about 14187-32-7, name: Dibenzo-18-crown-6
The macrocyclic compounds 1,6,7,14,23-pentaoxa<7,2> orthocyclo<2> (2,6)-pyridinophan; (DBP18C6) and 1,4,7,14,17,20-hexaoxa<7,7> ortocyclophan; (DB18C6), used as ligands in the complexes with Eu(ClO4)3 and Tb(ClO4)3, were examined.A series of absorption spectra of Eu(III)<*>DBP18C6 and Tb(III)<*>DBP18C6 complexes was obtained by spectrophotometric titration with the lanthanide ions as a titrant and using CH3CN and CH3OH as solvent at different volume ratios.The analysis of absorption spectra has shown a different influence of the mixed solvent on absorbance of the complexes investigated.An analogous investigation carried out with DB18C6 similar to DBP18C6 has led to the conclusion that the presence of pyridine ring in DBP18C6 influences the effects observed. Key words: lanthanides, macrocyclic polyethers, spectrophotometric titration, solvation
