摘要：

In this contribution we report on the preparation and characterisation of both 2,5-di-(9,9-dimethylfluoren-2-yl)-3,4-dihexyl-thiophene-1,1-dioxide and the corresponding polymer with longer alkyl substituents at 9 fluorene position. Optical and structural characterisations performed on both crystalline and amorphous films showed noticeable luminescence properties depending on the molecular aggregation. Both polymer and oligomer based LEDs showed external efficiency of more than 10(-1)%. C (C) 2003 Elsevier Science B.V. All rights reserved.
