| Abstract: | The four new cis(trans)-4,4'-bis(4-hydroxyphenylazo)dibenzo-14-crown-4 and cis (trans)-4,4'-bis(4-hydroxyphenylazo)dibenzo-18-crown-6 are synthesized via diazotization and coupling reactions by using cis(trans)-diaminodibenzo-14-crown-4 and cis (trans)-diaminodibenzo -18-crown-6 as raw materials. The structures of compounds are characterized by means of UV-vis,IR1H-NMR and elemental analysis. It is found that the melting points of compounds 2 and 4 having trans-configuration are higher than those of corresponding cis-configuration compounds 1 and 3. |
