Femtosecond charge transfer in assemblies of discotic liquid crystals
(2008) In Journal of Physical Chemistry C 112(40). p.15784-15790- Abstract
- The electronic coupling strength within columns of discotic liquid crystals is investigated using core-level Coexisting well-ordered and disordered regions are identified in thin films of tetra-alkoxy-substituted phthalocyanines with the aid of near edge X-ray absorption fine structure and photoelectron spectroscopies. These different regions Lire used to derive a lower limit for the intermolecular charge transfer bandwidth within the framework of the core-hole clock principle. We find average charge transfer times on the order of a few femtoseconds, that is, significantly faster than the C(1s) core-hole lifetime, which indicates a surprisingly strong electronic coupling between the phthalocyanine units as compared to what is expected from...
