<p>Polymer suitable for use in organic light-emitting devices A polymer comprises a repeat unit of formula (Ia): (Ia) wherein R7 represents a substituent bound to the 9-carbon atom of the fluorene ring through a non-aromatic carbon atom, R8, R9 and R" independently in each occurrence represent H or a substituent with the proviso that at least one R8 is not H; RI° independently in each occurrence is a substituent; and t in each occurrence is independently 0, 1, 2 or 3. The polymer may be used in the organic light-emitting devices.</p> |
