Several benzo- and/or naphtho-derivatives of triptycene were prepared in a manner of addition reaction of dehydronaphthalene (XIII) or a new type of aryne, dehydroanthraquinone (XVI) generated from 3-aminoanthraquinone-2-carboxylic acid (XV), with a few acenes. The absorption bands in longer wavelength region of their UV spectra and the chemical shift of bridgehead protons in their NMR spectra led
