In a series of thiaaceneporphyrinoids, their conformers exhibit macrocyclic pi-conjugation pathways controlled by a dihedral angle between the porphyrin framework and acene planes. Conformational equilibria significantly affect the photophysicalproperties of these macrocycles.

The reaction of anthracene-9,10-carboaldehyde with various Grignard reagents under ambient conditions gave 9,10-bis(1-hydroxyalkyl)anthracene-9,10-peroxides and 9,10-anthraquinone as the first example. The endoperoxidation of 9,10-bis(1-hydroxyalkyl)anthracenes was assisted by the lone paired electron of oxygen in the side chain, and the endoperoxides were transformed to anthraquinone by the Grignard reagents.
