Abstract
Monomeric 3-substituted tellurophene compounds, as well as their use in the synthesis of oligomeric and/or polymeric compounds consisting of two or more tellurophene-2,5-diyl groups which are covalently linked to each other are disclosed, as is the use of said oligomers and polymers in devices such as diodes and solar cells, electrodes and semiconductors.
Claims28
A compound of formula (5):
- wherein R represents a monovalent organic group, or a salt thereof, wherein when R is a linear unsubstituted alkyl, R is C2-C50 alkyl.
2-5. (canceled)
An oligomeric or polymeric compound comprising two or more tellurophene-2,5-diyl groups covalently linked to each other at one or the other of the 2- and 5-positions of each tellurophene ring, wherein each of the tellurophene rings is substituted at the 3- or 4-position thereof, wherein said compound is of formula (A):
- wherein n is an integer greater than 1;
- and
- each R is, independently of each other, a monovalent organic group other than a methoxy group, or a salt thereof.
