Photooxidation of Anthracene [PDF]

Bulletin of the Chemical Society of Japan, 1968
Abstract It was found that anthracene (I) was converted to 9,10-anthraquinone (III) and bianthrone (IV) by irradiation via anthracene peroxide (II). The reaction proceeded most effectively in carbon disulfide. Also IV was found to be oxidized to III by oxygen in singlet state.

Butterfly-shaped Dibenz[a,j]anthracenes: Synthesis and photophysical properties [PDF]

, 2023
A strategy for the synthesis of dibenz[a,j]anthracenes (DBAs) from cyclohexa-2,5-diene-1-carboxylic acids is presented. Our approach involves sequential C–H olefination, cycloaddition, and decarboxylative aromatization.

Jet spectroscopy of anthracene and deuterated anthracenes [PDF]

The Journal of Chemical Physics, 1984
Fluorescence excitation and SVL fluorescence spectra of jet-cooled h10-, 9d1-, 9,10d2-, and d10- anthracene are reported. Ground state vibrational assignments are presented for all these species and are compared with literature values. In addition, assignments for the first excited singlet state of h10- anthracene are made using SVL spectra and ...

Kinetic Stabilization of Blue‐Emissive Anthracenes: Phenylene Bridging Works Best

, 2021
In attempts at kinetically stabilizing blue‐emissive anthracenes, a series of 9,10‐diaryl substituted derivatives were tested for their photochemical and photooxidative persistence.
