Compounds according to Formula 1, devices containing the same and formulations containing the same are described. Formula 1 has the following structure: n n n n n n n n n n n n where at least two of R 1 -R 10 are not H, n where at least one of R 1 -R 10 has the formula T1 n n n n n n n n n n n n n n n n where L is an organic linker, n where Y 1 to Y 4 are CR or N, n where adjacent R moieties can form fused rings, n where R s and R t are independently aryl or heteroaryl, either of which may independently be further substituted, and n where R s and R t do not form fused rings with any part of the molecule. |
