Abstract

Efficient emissive fluorene-based p–n conjugated porous materials (CPMs) have been constructed via an effective Friedel–Crafts green polymerization. For metal-free and room-temperature processing, CPMs exhibit high fluorescence quantum efficiency of 32%, allowing the fabrication of near-white polymer light-emitting diodes with CIE of (0.30, 0.38).
