Photoprocesses in 1,4-diazadistyrylbenzene ( 1 ) and 1,3-diazadistyrylbenzene derivative ( 2 ) diperchlorates in MeCN were studied by absorption, luminescence, and kinetic laser spectroscopies. For compound 1 , trans-cis -photoisomerization and intersystem crossing to a triplet state are observed. For compound 2 , photoelectrocyclization is suggested. Quantum chemical calculations of diazadistyrylbenzene structures in the ground and excited states were carried out. The schemes for photoreactions were proposed.
