Abstract: Syntheses of 9-alkyl-3-phenylazocarbazole and its analogues containing
azomethine and ethylene bridges were described. The dipóle moments of
these compounds were measured in benzene solutions and compared with
those of 9,9'-diethyl-3,3'-azocarbazole and 9-methyl-3-carbazolylazonitrile.
Explanations of very high dipóle moment of the azocarbazole and the ease
of the thermal transition of its cis to trans isomer are proposed.
