The photochemistry and photophysics of papaverine N‐oxide in polar aprotic and protic solvents has been studied in detail. Complex energy and charge‐transfer phenomena between chromophores occur in papaverine. New photochemistry for the papaverine N‐oxide system is reported. Irradiation in protic media results in the formation of an emissive charge‐transfer state with ensuing intramolecular hydroxylation
已详细研究了罂粟碱 N-氧化物在极性非质子和质子溶剂中的光化学和光物理。罂粟碱中发生发色团之间复杂的能量和电荷转移现象。报道了罂粟碱 N 氧化物系统的新光化学。质子介质中的辐照导致形成发射电荷转移状态,随后以高分离产率(75-80%)进行分子内羟基化。
