Using 4-connected pyrene-based building blocks with D2h symmetry and 2-connected fluorene-based linker with C2v symmetry, a 2D porous organic framework is obtained via imine condensation, PAF-130. PAF-130 has high crystallinity, permanent, and a high photoluminescence quantum yield, which is as high as 29.5% when dispersed in acetonitrile.
