Abstract
Molecular design of analogues of benzo[1,2,3-kl:4,5,6-k'l']dixanthene and anthra[1,9-bc:4,10-b'c']dichromene containing sulfur or nitrogen i nstead of oxygen was performed. The calculated absorption maxima of co mpounds containing oxygen or sulfur appeared in the similar region, wh ile, those of their analogues containing nitrogen shifted to longer wa velengths. We have synthesized several new heterocyclic analogues and compared the observed wavelengths with the calculated ones.
