    Self-Assembled Triple-Stranded Lanthanide Dimetallic Helicates with a Ditopic Ligand Derived from Bis(benzimidazole)pyridine and Featuring an (4-Isothiocyanatophenyl)ethynyl Substituent
    摘要:
    Bis(2-{6-(diethylcarbamoyl)-4-[(4-isothiocyanatophenyl)ethynyl]pyridin-2'-yl}-1-ethylbenzimidazol-5-yl)methane (L-G) reacts with trivalent lanthanide ions in acetonitrile to yield triple-stranded dimetallic helicates [Ln(2)(L-G)(3)](6+). H-1-NMR Data point to the helicates being the only species formed under stoichiometric conditions and having a time-averaged D-3 symmetry on the NMR time scale. The photophysical properties of L-G and its helicates are discussed with respect to the closely related ligands L-B, L-E, and their complexes, two ligands devoid of the isothiocyanatophenylethynyl substituent. ne quantum yield of the ligand fluorescence is three times smaller compared to L-E, while that of the Eu(III)centered luminescence (1.1%) is three times larger. On the other hand, the luminescence of Tb-III is not sensitized by L-G. This is explained in terms of energy differences between the singlet and triplet states on one hand, and between the 0-phonon transition of the triplet state and the excited metal ion states on the other. This work demonstrates that bulky substituents in the 4-position of the pyridine ring do not prevent the formation of triple-stranded helicates, opening the way for luminescent probes that can easily be coupled to biological materials.

    摘要:
    合成了双{1-乙基-2-[6-(N,N-二乙基氨基甲酰基)-4-卤代吡啶-2-基]苯并咪唑-5-基}甲烷(卤素=氯,LE;溴,LF)作为双位受体,用于开发能够与生物材料耦合的含镧元素的螺旋体,并测试卤代取代基对包裹过程、所形成的双金属构筑物结构以及封装离子的光物理特性的影响。通过NMR竞争滴定法确定的[Eu2(L)3]6+螺旋体的稳定性与未取代配体(LB)相比,分别下降了一个(LF)和三个(LE)数量级,尽管其仍然较大,在乙腈中log β23为23.8(LF)和21.8(LE)。在乙腈中,[Ln2(LE)3]6+螺旋体在镧系元素(Pr到Yb)间显示出同构性,[Tb2(LB)3]6+的晶体结构似乎是它们溶液结构的良好模型,通过顺磁性NMR测量(镧诱导位移法)和弛豫时间测定得以证明。配体LE对EuIII的灵敏度相当,其量子产率比[Eu2(LB)3]6+大25%。但 ligand 3ππ*状态与Tb(5D4)激发态之间存在共振,这限制了TbIII的敏化。在溶液和固态下,[Eu2(LE)3]6+的高分辨率发光光谱被呈现并讨论,涉及位点对称性和声子耦合机制的问题。
