文摘
- •
Synthesis and characterization of A-π-D phenanthroimidazole dye are described.
- •
The dye exhibits positive solvatochromism.
- •
The prototropic study indicates formation of a mono- and dication upon protonation.
- •
One- and two-photon excitation leads to trans-cis isomerization.
- •
The trans-to-cis isomerization is followed by decomposition of the compounds.
