Tunable photo-luminescence behaviors of macrocycle-containing polymer networks in the solid-state.

Two porous polymers were synthesized from tetraphenylethylene (TPE) crosslinked β-cyclodextrins (β-CD) and sulfonatocalix[4]arene (SC4A). Owing to the FRET process from the TPE to the encapsulated fluorophores, these polymers provide universal platforms for the fabrication of photo-luminescence tunable organic solid materials.
