Green-synthesized single-benzene fluorophores exhibiting room-temperature phosphorescence and solid-state fluorescence for biological and optical applications

Single-benzene fluorophores (SBFs) offer a minimalistic access to very small, bright, and electronically tunable emitters via push-pull effects. Herein, we report a green, solvent-free SNAr reaction of tetrafluoroterephthalonitrile (TFTPN) with...
