A soluble conjugated–non-conjugated oligoazomethyne, namely oligo[(oxyoctyleneoxy-(2,6-dimethoxy-1,4-phenylenemethylidinonitrile-6-phenyl-1,3,5-triazine-2,4-nitrilomethylidine)], was synthesized through the reaction of 1,8-bis(4-formyl-2,6-dimethoxyphenoxy)octane and 2,4-diamine-6-phenyl-1,3,5-triazine. Fluorescence and excitation spectra in solution and in the solid state brought evidence of strong...
Steady-state fluorescence spectra and time correlated single-photon counting measurements were performed on samples of poly(vinyl alcohol), poly(vinyl acetate) and their blends in different proportions (91, 11 and 19) containing fluorescein and/or anthracene probes. The interface thickness, the surface to volume ratio of microdomains and the heterogeneity of the samples were determined from those...
