亲水性咔唑共聚物和钼簇合物之间的作用及其溶液荧光

Interaction between Hydrophilic Carbazole Copolymer and Molybdenum Cluster Compound in Solution and Its Fluorescence

研究了Ｎ－ 乙烯基咔唑－ 丙烯酸共聚物（ ＮＶＣ－ ＡＡ） 和微量的钼簇合物［ Ｍｏ３ Ｏ２（Ｏ２ＣＣＨ３） ６（ Ｈ２ Ｏ） ３］ Ｂｒ２ ·２Ｈ２ Ｏ 在水溶液相互作用及其溶液荧光。实验发现， 体系中存在单体荧光（３７５ ｎｍ） 和二聚体激态缔合物荧光（５００ｎｍ） 。荧光强度分别随钼簇合物的浓度增加和ｐＨ 值的提高而增强。

The interaction between hydrophilic N _ vinylcarbazole and acrylic acid(NVC-AA) copolymer and trace amount of molybdenum cluster compound, [Mo3O2(O2CCH3)6(H2O)3]Br2·2H2O, in solution and its fluorescence were investigated. When the trace amount of molybdenum cluster compound is added into the aqueous solution of NVC-AA, there exist monomer fluorescence(λem=375 nm) and excimer fluorescence (λem=500 nm). The excimer fluorescence intensity increases with the increasing pH value and amount of molybdenum cluster compound.
