以高收率设计和制备了预先组织好的用于金属离子结合的新的含膦酰基的四齿杂环。两个带有膦酰基的2,2'-联吡啶和菲咯啉配体的X射线结构,以及2,6-双(二苯基膦酰基)吡啶和9-(二苯基膦酰基)-1,10-菲咯啉-的紧密相关结构报告为2个。几个镧系元素及Eu的三氟乙酸盐的硝酸盐的复合物(III)分离并鉴定了两个带有膦酰基的2,2'-联吡啶和菲咯啉配体。报道了具有膦酰基,2,2'-联吡啶和菲咯啉配体的镧系元素配合物的第一结构。抗衡离子的性质对于金属离子的配位环境至关重要。研究了在配体和抗衡离子的性质上都不同的配合物的光物理性质。配合物的光物理性质强烈依赖配体和抗衡离子。配合物的吸光度和发光激发光谱显示出在UV范围内的主峰,其对应于配体对光的吸收,并且是依赖于配体的。配合物的发光光谱显示红色区域具有典型的euro发射,且量子产率高,5 D 0 → 7 F J( J = 0-6)。从反型中心跃迁的5 D
The "flexible" 3 and "rigid" cyclic viologens 4, diquarternary salts of 2,2'-bipyridine and 1,10-phenanthroline, respectively, were treated with tributylphosphine (1) in acetonitrile containing a large amount of methanol under an argon atmosphere. A single electron transfer (SET) easily occurred from the latter to the former, the SET to 4 being 10(5)-10(6) times faster than the SET to 3. The reorganization

The molecular binding behavior of sulfonated calixarenes with phenanthroline-diium guests were systemically investigated. p-Sulfonatothiacalix[4]arene shows a high affinity with phenanthroline-diium guests in the order of magnitude of 105 M−1.
