We succeeded in synthesizing edge-brominated zeolite-templated carbon (ZTC-Br) as the key intermediate of edge-functionalization of ZTC via an electrophilic aromatic substitution reaction using dibromoisocyanuric acid. ZTC-Br was easily converted into carbazole-modified ZTC (ZTC-Cz) using Suzuki-Miyaura coupling. Interestingly, solvent-dependent changes of the fluorescence intensity of ZTC-Cz owing to its swelling shrinking behavior were observed.
