Novel two-dimensional octupoles containing azo groups and their oligomers have been synthesized and their first hyperpolarizabilities were determined. The λmax and β(0) values of azo octupoles are nearly the same regardless of the nature of the

The spectra of 27 substituted 4-N,N-diethylaminoazobenzenes are determined.The band system can be separated by deconvolution into two Gaussian curves.The results so obtained show that the effects of substituents on n-->?* and ?-->?* transitions are similar and that electron withdrawing substituents in the phenylazo residue cause a bathochromic shift of both the n-->?* and the ?-->?* bands.
