According to Willianmson reaction for the synthesis of crown ether ring, a very important intermediate, alkoxy-chain linked two triphenylene moieties was synthesized successfully through a slow addition of bis(2-chloroethyl) ether to avoid the production of crown ether ring on single triphenylene from 2,3-dihydroxy-tetrakis(pentyloxy)-triphenylene. Furthermore, a crown ether bridged triphenylene dimer was finally achieved via the condensation reaction of bis(2-chloroethyl) ether with the intermediate. The final product was characterized by ¹H NMR, ¹³C NMR and MALDI-TOF spectra.

Key words: Willianmson, triphenylene, dimer, crown ether
