Abstract:
Polymers comprising at least one unit of formula (1) wherein n is 0 or 1, m and p are independently from each other 0,1,2,3,4,5 or 6, provided that the sum of n, m and p is at least 2, and n and p are not 0 at the same time, Ar 1 and Ar 2 are independently from each other C 6-14-arylene or C 6-14-aryl,which may be substituted with 1 to 4 substituents independently selected from the group consisting of C 1-30-alkyl, C 2-30-alkenyl, C 2-30-alkynyl, C 5-8-cycloalkyl, C 6-14-aryl and 5 to 14 membered heteroaryl, and X 1,X 2 and X 3 are independently from each other and at each occurrence O or S, compositions comprising these polymers, and electronic devices comprising a layer formed from the compositions. Preferably, the electronic device is an organic field effect transistor and the layer is the dielectric layer.
Abstract:
Disclosed are polymers comprising at least one unit of formula (1), a process for their preparation, intermediates and electronic devices comprising these polymers as semiconducting material.
Abstract:
The present invention relates to compounds of the formula (I) where R1 and R2 independently of each other, are selected from 1H,1H-C2-C10- perfluoroalkyl and 1H,1H,2H,2H-C3-C10-perfluoroalkyl,except for the compound of formula (I), where R1 and R2 are both 1H,1H-perfluorobutyl, and to their use, especially as an n-type semiconductor.
