Multi-block copolymers based on an asymmetric light emitting diode, suitable polymers and oligomers (MULTI-BLOC COPOLYMER BASED TUBULAR LIGHT EMITTING DIODE, POLYMERS SUITABLE THEREFOR AND OLIGOMERS)

摘要

The present invention comprises at least one block copolymer consisting of an electroluminescent material, an electrode, optionally a carrier material and / or a reflective material, wherein the electroluminescent material is comprised of at least two types of blocks of active blocks sandwiched between inactive blocks Wherein the active block is a -conjugated block of units of at least 2 and up to 16 monomers, wherein the -conjugated block has a substantially uniform block length throughout the copolymer, (LED) that emits light having a wavelength of 400 to 850 nm consisting of a passive block having non-pi-conjugation.
