Photoexcitation dynamics in regioregular and regiorandom polythiophene films
Using a variety of optical probes techniques we studied the photoexcitation dynamics in thin films of poly-3-hexyl thiophene with regioregular order that forms lamellae structures with increased interchain interaction, as well as regiorandom order that keeps a chainlike morphology. In regiorandom films we found that intrachain excitons with correlated induced absorption and stimulated emission ...

SWNT-porphyrin/phthalocyanine conjugates are described and fully characterised; their optical and electrochemical properties are investigated.
متن کاملPhotoexcitation dynamics in polyconjugated molecules
π-conjugated polymers have become an important class of materials for electronic devices. Design of these devices requires understanding such processes as photochemical reactions, spatial dynamics of photoexcitations, and energy and charge transport, which in turn involve complex coupled electron-vibrational dynamics. Here, we study photoexcitation dynamics in of several conjugated polymers usi...
متن کاملOptical Studies in Magnesium Phthalocyanine, Iron Phthalocyanine and Zinc Phthalocyanine Thin Films
Spectral studies of metal phthalocyanines are invaluable in the understanding of the electronic processes in phthalocyanines. The electronic overlap between the centrally substituted metal ion and the phthalocyanine ring can be observed from charge transfer (CT) transition between the central metal ion and the phthalocyanine ligand and point to extensive coupling between the two electronic syst...
متن کاملAsymmetric grain distribution in phthalocyanine thin films
Many electronic and optical properties of organic thin films depend on the precise morphology of grains. Iron phthalocyanine thin films are grown on sapphire substrates at different temperatures to study the effect of grain growth kinematics and to experimentally quantify the grain size distribution in organic thin films. The grain size is measured with an atomic force microscope and the data i...
