Stilbazolium salts as fluorescence probes f or monitoring local viscosity and pH of solutions
Journal Title: CHEMIK nauka-technika-rynek - Year 2011, Vol 65, Issue 4
Abstract
A series of p-substituted 2- or 4-styrylquinolinium iodides and 2- or 4- styrylpyridinium iodides were prepared by the condensation of 4-(N,N-dimethylamino)benzaldehyde and 4-(N,N-dimethylamino)- 1-naphthaldehyde with N-substituted picolines and methylquinolinium iodides. Spectroscopic properties of the dyes are characterized in organic solvents. These dyes were then tested as fluorescence probes to study the local viscosity and pH of the solutions.
