magnetically uncoupled [4+4] photocycloaddition product. Density functional calculations give further insights on the intramolecular (“pseudo-bimolecular”) photocycloaddition reaction of the two facing 2,6-anthracene or 1,5-naphthalene spacers in this novel family of dicopper(II) oligoacenophanes. The unique ability of oligoacenes as photoswitchable antiferromagnetic wires between two CuII ions separated
摘要 金属环烷型双核铜 (II) 配合物 (nBu4N)4[Cu2(2,6-anba)2] (1) 和 (nBu4N)4[Cu2(1,5-naba)2]·4H2O ( 2) 报道了具有光活性的 2,6-蒽-(2,6-anba) 和 1,5-萘双(草酸酯) (1,5-naba) 桥连配体。它们在中等强度的反铁磁耦合二铜 (II) 物质和相应的磁性非耦合 [4+4] 光环加成产物之间进行热可逆的固态光磁 (ON/OFF) 切换。密度泛函计算进一步了解了这种新型二铜 (II) 低聚苯并苯中两个面对 2,6-蒽或 1,5-萘间隔基的分子内(“伪双分子”)光环加成反应。
