The photoconductive properties of an azo-containing [2]rotaxane, bearing a π-conjugated axial part and its corresponding dumbbell compound are investigated. Structural effects on the observed photoconductive behavior in both cases are discussed. The photoresponsive behavior of the title [2]rotaxane was proved to be more intense than that of its analogue(More)
This work deals with the design, synthesis, and characterization of a new solvatochromic dye. The intense solvatochromic behavior of this new synthesized non symmetric viologen was investigated using UV-Vis spectrophotometry. A further purpose was the study of the interactions between the solvent and solute molecules responsible for the solvatochromism.(More)
