Two-color sum frequency generation study of poly(9,9-dioctylfluorene)/electrode interfacesElectronic supplementary information (ESI) available: Details of the experiment, theoretical description, and the fitting summary. See DOI: 10.1039/c0cp00838a

The air/PFO and the buried electrode/PFO interfaces have been investigated by two-color SFG spectroscopy. Due to the interface confinement effects, the planes of PFO rings are nearly parallel to the surface plane, and the optical band gaps become smaller at the interfaces than those of the bulk. The...

Description
Summary:The air/PFO and the buried electrode/PFO interfaces have been investigated by two-color SFG spectroscopy. Due to the interface confinement effects, the planes of PFO rings are nearly parallel to the surface plane, and the optical band gaps become smaller at the interfaces than those of the bulk. The vibrational and the electronic structures of air/PFO and the buried electrode/PFO interfaces have been investigated by interface-sensitive two-color SFG spectroscopy.
