From Static to Dynamic: Electron Density of HOMO at Biaryl Linkage Controls the Mechanism of Hole Delocalization [PDF]
, 2018 In order to extend the physical length of hole delocalization in a molecular wire, chromophores of increasing size are often desired. However, the effect of size on the efficacy and mechanism of hole delocalization remains elusive.

Angewandte Chemie, EarlyView.Die geminale Difunktionalisierung leicht verfügbarer Bausteine ermöglicht einen schnellen Zugang zu molekularer Komplexität. Diese Arbeit stellt eine Strategie vor, um zwei unterschiedliche funktionelle Gruppen an einem Carbonylkohlenstoff zu installieren, indem dieser in eine Donor–Donor‐Diazo‐Verbindung überführt wird. Die Methode ist sowohl im Batch‐

Folic Acid With Fluorene: A Complexation Study by UV and FTIR Spectroscopies
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017 The complexation between folic acid and a typical polyaromatic hydrocarbon, fluorene, was investigated using FTIR and UV spectra. Appearance of a new IR band at 2401cm−1 demonstrates that NH2–C=N moiety on pterin ring in folic acid is protonated ...

X-ray Raman scattering study of aligned polyfluorene [PDF]
, 2006 We present a non-resonant inelastic x-ray scattering study at the carbon K-edge on aligned poly[9,9-bis(2-ethylhexyl)-fluorene-2,7-diyl] and show that the x-ray Raman scattering technique can be used as a practical alternative to x-ray absorption ...
