Abstract

3'-dimethyl-9

9'-bianthracene was synthesized from 2-methyl-anthraquinone through two steps reactions

and its structure was determined by means of

H NMR spectra and elemental analysis. The synthetic pathway has more advantages such as few reaction steps

high yield

easy purification and so on. Moreover

the effects on the reaction yield by different reductants and mole ratios were also discussed and its optical properties were characterized by the absorption and photoluminescence (PL) spectra. The results indicated that the maximum emission peak of the compound is at 447 nm

which is the typical blue fluorescence and its fluorescence quantum yield is 1.18 times than that of 9

9'-bianthracene.
