Our results show that the oligofluorene thin films deposited at substrates of different temperatures will alter the electronic structures, which results from the change of interunit angles in 2,7-bis[9,9-di(4-methylphenyl)-fluoren-2-yl]- 9,9-di(4-methylphenyl)fluorine molecules. The fluorene-units at low temperature are almost perpendicular to each other and the interunit angle of stable state is 41° at room temperature. © 2009 American Institute of Physics. |
