General description

Red Light-Emitting Spiro-Copolymer (Livilux® SPR-001) is a cutting-edge emissive material with an average molecular weight of 720,000, specifically engineered for use in organic light-emitting diodes (OLEDs) and polymer light-emitting diodes (PLEDs). This polymer exhibits exceptional optical properties, delivering vibrant red emission that enhances display quality. With its low operating voltage and outstanding solubility in various organic solvents, it provides versatility and ease of use for researchers and developers in the electronic materials sector.

Preparation Note: For optimal results, prepare a solution of the spiro-copolymer at a concentration of 11 g/L in toluene for spin-coating applications. For inkjet printing, a special formulation is required. It is essential to conduct all preparation procedures in a nitrogen atmosphere to maintain the stability and performance of the polymer.

Application

Features:
  • Soluble spiro-copolymer
  • Long lifetime with further big potential to improve
  • Saturated red color coordinators
  • Low operation voltage
