TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The oligomer or polymer base scaffold comprises no functional unit and the fluorine-bridged associate comprises three types of compounds with a fluorine residue. The oligomer or polymer base scaffold comprises hole transport- and/or hole injection unit and the fluorine-bridged associate comprises an electron transport-, electron injection unit and/or an emitter unit as compound(s) with a fluorine residue. The oligomer or polymer base scaffold comprises electron transport- and/or electron injection unit and the fluorine-bridged associate comprises hole transport-, hole injection unit and/or an emitter unit as compound(s) with a fluorine residue. The oligomer or polymer base scaffold comprises emitter unit and the fluorine-bridged associate comprises hole transport-, hole injection unit, electron transport- and/or electron injection unit as compound(s) with a fluorine residue. The oligomer or polymer base scaffold comprises hole transport- and/or hole injection unit and electron transport- and/or electron injection unit and the fluorine-bridged associate comprises emitter unit as compound(s) with a fluorine residue. The oligomer or polymer base scaffold comprises hole transport- and/or hole injection unit and emitter unit and the fluorine-bridged associate comprises electron transport- and/or electron injection unit as compound(s) with a fluorine residue. The oligomer or polymer base scaffold comprises electron transport- and/or electron injection unit and emitter unit and the fluorine-bridged associate comprises hole transport- and/or hole injection unit as compound(s) with a fluorine residue. The oligomer or polymer is: non-conjugated or partially conjugated homo- or co-oligomer or -polymer; or conjugated homo- or co-oligomer or -polymer. The co-oligomer or -polymer is a statistical co-oligomer or polymer, an alternating co-oligomer or -polymer or a block co-oligomer or -polymer. The oligomer contains 3-9 or greater than or equal to 10 repeating units. The fluorine residue is of formula (CxHyFz), preferably F, CF3, C2F5, CF3 (CH2)aS, CF3CF2S or (CF3-(CH2)a)2N. The emitter is a triplet emitter. In the oligomer or polymer, a spacer is present between the oligomer or polymer base scaffold and fluorine residue.x = greater than or equal to 0;y = greater than or equal to 0;z = greater than or equal to 1, where optionally one or more non-adjacent CH2 groups are substituted by O, S, Se, Te, Si (R1)2, Ge(R1)2, NR1, PR1, CO or P(R1)O; eitherR1 = alkyl, alkenyl, alkynyl, aryl, arylalkyl, arylalkenyl, arylalkinyl, heteroaryl, or heteroalkyl, where one or more non-adjacent carbon atoms of the non-aromatic portion are optionally substituted by O, S, COO or OCO; or2R1 = ring system; anda = 0-5.
