Interface specific variations in the steady-state optical properties of polyfluorene thin films

The top and bottom interfaces of spin cast poly(di- n -octylfluorene) (PF8) and poly[bis(2-ethylhex-yl)fluorene] (PF2/6) films are investigated by optical absorption and emission spectroscopy. In this study both the pure polyfluorene homopolymers and random copolymers comprised of linear di- n -octy...
