• Two green emission SPPs were formed by utilizing the non-bonding self-assembly.
• These SPPs exhibit good thermal properties with high glass-transition temperature.
• The photo- and electro-luminescent properties are dependent on the hosts' structure.
In order to develop a novel class of solution-processable electroluminescent (EL) emitters, a bis(dibenzylammonium)-tethered host was synthesized and two green emission supramolecualr phosphorescent polymers (SPPs) were formed by utilizing the efficient non-bonding self-assembly between bis(dibenzo-24-crown-8)-functionalized iridium complex and bis(dibenzylammonium)-tethered monomers. The photophysical, thermal and electroluminescent properties of the SPPs were discussed in detail. These SPPs exhibit good thermal properties with high glass-transition temperature (Tg). The photophysical and electroluminescent properties are strongly dependent on the host unit structure of supramolecular polymers. The present work may provide a useful way to afford a new class of high-performance electroluminescent emitters for green emission PLEDs.
