Abstract

A large band gap supramolecular polymer based on host–guest interactions was developed as the host material for phosphorescent organic light-emitting diodes. The dibenzo-24-crown-8, and dibenzylammonium salt functionalized fluorene-based large band gap compounds 1 and 2 were developed as the host and guest monomers, respectively. The resulting linear supramolecular polymer (SP) 3 was obtained from the self-organization of the host and guest monomers, which was validated by nuclear magnetic resonance, viscosity and differential scanning calorimetry studies. The SP 3 maintained the triplet energy level of the host monomer 1 and the guest monomer 2. The resulting device based on the supramolecular host material and a yellow-phosphorescent complex Ir(Flpy)3 achieved a maximum luminance efficiency of 18.2 cd A−1.
