Compositions of conjugated polymers, applicable to many electronic fields.
Polymeric conductors have been incorporated into a wide variety of electronic and optical materials and devices. Solution processing is a simple, economical, and controllable approach to depositing layers of conjugated polymers. Traditional manufacturing methods typically involve only one solution processing step for depositing polymers. However, single-solution processing presents a difficulty in preparing multilayer materials, as most conjugated polymers are soluble in organic, nonpolar media. Multilayer devices offer optimal performance, but depositing multiple layers with similar solubility results in interfacial mixing which adversely affects the device’s reproducibility, structure, and efficiency.
• Prevents interfacial-mixing in devices
• Improved ability of polymers transporting electrons
• Soluble in polar media such as water and methanol
• Polymer light-emitting diodes (PLEDs)
• Optoelectronic materials and devices
