Abstract
A series of novel fluorescence carbazole-functionalized building blocks with increased π-conjugated systems have been synthesized and investigated as potential candidates for carrying out complex formation reactions with metal salts. The combination of data obtained from elemental analysis, IR and NMR spectroscopy, mass-spectrometry and GPC allows us to confirm the suggested linear and bulky dendron's structures. The chemical modification of dendrons with functional groups affects the thermal stability phase behavior and fluorescent properties. Dendrons showed the positive solvatochromism effect, which was confirmed by the red shift when the polarity of the solvents was increased. The fluorescence lifetime for dendrons of the first and second generation decreases with decreasing solvent polarity. The study of the spectral properties of compounds in the solid state showed that the synthesized molecules exhibit bluish-white fluorescence.
