Abstract: The invention relates to conjugated polymers containing triptycene units. The polymers according to the invention are on the one hand homopolymers comprising a recurring unit containing a triptycenylene radical, and copolymers comprising two or more different recurring units, which may contain a triptycenylene radical or an arylene, heteroarylene, vinylene and ethynylene radical. The polymers according to the invention are employed as electroluminescent materials.

Abstract: Triptycene derivatives, and their use for opto-electronic applications, in particular as electroluminescent materials Triptycene devices of the formula (I) where the symbols in the formula have the following meanings: K1, K2 and K3 are identical or different and are mono- or polycyclic systems, which may, if desired, contain heteroatoms, preferably N, S and/or O, and; X and Y are identical or different and are CR1, N, P, As or SiR2; R1 are identical or different and are H, halogen, pseudohalogen or a hydrocarbon radical having 1 to 30 carbon atoms, which may also, if desired, contain heteroatoms, preferably —O—, —N— and/or —S—; R2 are identical or different and are a hydrocarbon radical having 1 to 30 carbon atoms, which may also, if desired, contain heteroatoms, preferably —O—, —N— and/or —S—, are suitable for use in electroluminescent devices.

Abstract: The invention features a functional polymer which provides three primary colors and is free from aggregation of high molecular chains. The functional polymer is obtained by copolymerization of fluorene unit and acene unit having three or more benzene rings or hetero rings, and has the structure denoted by the following formula: wherein A through H are selected from alkyl, thioalkyl, alkoxy, aryl, aryloxy, or the like; I and K through W are selected from C, O, N, P, S, and Si, R1 and R2 are selected from alkyl (iso or normal), cycloalkyl, acyl, or the like; p and q are integer numbers which satisfy p+q≧2; and n and m are integers equal to or greater than 1.
