Star-shaped conjugated oligomer T3HTP containing pyrene, 3-hexylthiophene and triphenylamine, has been successfully synthesized via a simple one-pot sequential direct arylation process. The chemical structure and optical properties of T3HTP oligomer were characterized via proton nuclear magnetic resonance (1H-NMR), UV-Vis and fluorescence spectroscopies. The results indicated that T3HTP oligomer showed good fluorescence quenching toward TNT, which is useful for identifying explosive nitro aromatic compounds.
