Synthesis and Photophysical Characterization of Novel pi-Conjugated Vinyl Sulfides
The synthesis and photophysical properties of a series of π-conjugated vinyl sulfides are described. These compounds exhibited their absorption maxima in the range of 350–366 nm, while the emission spectra displayed peaks in the zone of 421–441 nm; both of them were influenced, although in different...

| Sumario: | The synthesis and photophysical properties of a series of π-conjugated vinyl sulfides are described. These compounds exhibited their absorption maxima in the range of 350–366 nm, while the emission spectra displayed peaks in the zone of 421–441 nm; both of them were influenced, although in different degrees, by the extent of the conjugated system. Red-shifted absorption and emission were observed when the π-conjugation was extended, clearly indicating that the sulfur atom participates as a bridge within these highly conjugated structures. Therefore, this preliminary investigation suggests that vinyl sulfide-based π-conjugated materials are promising compounds for the development of novel and efficient organic emitters. |
