Design and Synthesis of Push–Pull Chromophores: Effects of Conjugation Types on the Optoelectronic Properties

Chromophores in Molecular Nanorings: When Is a Ring a Ring?

The topology of a conjugated molecule plays a significant role in controlling both the electronic properties and the conformational manifold that the molecule may explore. Fully π-conjugated molecular nanorings are of particular interest, as their lowest electronic transition may be strongly suppressed as a result of symmetry constraints. In contrast, the simple Kasha model predicts an enhancem...

Optoelectronic Properties of PbS Films: Effect of Carrier Gas

In this study, lead sulfide (PbS) films were grown on Fluorine-doped TinOxide (FTO) glass substrate by thermal evaporation in a horizontal furnace toinvestigate carrier gas effect on structural, morphological, elemental, optical, electricaland photovoltaic properties of PbS. X-ray diffraction (XRD) patterns confirmed theformation of cubic polycrystalline PbS particles fo...

Non-aromatic endocyclic angle at the ring fusion with the aromatic ring in benzocyclopentene and -hexene, revisited.

X-ray geometries of monocycloalkenobenzenes with a fused-ring size of r = 5, 6 were obtained by the use of the Cambridge Structural Database. In contrast to Allen's study [Acta Cryst. (1981), B37, 900-906], the data were not averaged over exact or imposed m(ad) symmetry (m(ad) is the mirror plane going through the midpoint of the aromatic ring fusion bond and the aromatic bond parallel to it). ...

Anomalous Optoelectronic Properties of Chiral Carbon Nanorings…and One Ring to Rule Them All23

Carbon nanorings are hoop-shaped, π-conjugated macrocycles that form the fundamental annular segments of single-walled carbon nanotubes (SWNTs). In a very recent report, the structures of chiral carbon nanorings (which may serve as chemical templates for synthesizing chiral nanotubes) were experimentally synthesized and characterized for the first time. Here in our Letter we show that the excit...
