Özet
The 6-hyroxyquinoline (HQ) was shown to undergo an oxidative oligomerization reaction in the alkaline medium. The obtained oligo (6-hyroxyquinoline) (OHQ) was characterized with respect to chemical composition, molecular weight, particle size, thermal stability, morphology and conductivity. FT-IR and H-1-NMR spectral data suggested that the resulting product was mainly C2, C4 and C6-coupled via C-C/C-O-C linkages. OHQ emitted white light upon irradiated at 339 nm. Optical band gap (E-g) of OHQ was determined to be 2.78 eV. The isolated product was amorphous and soluble in common polar organic solvents. The solid state conductivity studies for OHQ were also performed and found to be in the region of semiconductor.
