AbstractWe present a comprehensive study of the optical and electronic properties of a series of oligothiophenes in which one or two inter-ring torsional angles have been blocked by chemical bridging. These give us the possibility to investigate the role of the conformational mobility and of the coupling with the inter-ring torsion on the deactivation process of the singlet excited states. We find that both the radiative and the non-radiative deactivation channels are affected by the inter-ring bridging.

This study puts forth a new π-electron molecular scaffold containing two phenazine moieties connected by a four-membered ring. It exhibits interesting optical and electronic properties and sheds light on the role of the four-membered ring in conjugation.

The roles of N and Bi doped CQDs have been checked. N-doping resulted in exclusive optical and electronic properties in the CQDs while preserving their intrinsic properties such as quantum size effect, surface area and compatibility.

ZnS:Cu films were synthetized by co-sputtering. A Cu content higher than 10.6 at% lead to changes as the shrinkage of the ZnS:Cu cell and development of a p-type behavior. These results are explained by the substitution of Zn+2 ions by Cu+ ones.
