The magnetic field effects (MFE) on the lifetimes of triplet biradicals generated from the intramolecular photoreaction of bifunctional chain molecules, α-(4-benzoylphenoxy)-ω-[4-(phenylamino)phenoxy]alkanes (BP–O–n–O–DPA, n=2–16) were studied by laser flash photolysis. MFE on the biradical lifetimes are strongly affected by magnetic field, chain length, and solvent. The effects are interpreted in
双功能链分子α-(4-苯甲酰基苯氧基)-ω-[4-(苯基氨基)苯氧基]烷烃(BP-O-n-O)的分子内光反应产生的三线态双自由基寿命的磁场效应(MFE) –DPA, n=2–16) 通过激光闪光光解进行研究。双自由基寿命的 MFE 受磁场、链长和溶剂的强烈影响。根据高频松弛机制来解释效果。在n=2和4的双自由基中观察到由于T--S能级交叉导致的寿命变化。当n≥6时,双自由基发生单线态和三线态简并。
