framework designed for the preparation of luminescent lanthanide(III) complexes are reported. Eight ligands were designed and synthesized using different strategies, including alkylation reactions, amide couplings, and Ugi multicomponent reactions. All the ligands bear carboxylate groups for the coordination of the lanthanide(III) ions, with the lanthanide(III)‐sensitizing units consisting of the Tröger's
本文中,报道了具有Tröger基本框架的多足配体的第一族的合成和表征,该框架设计用于制备发光镧系元素(III)配合物。使用不同的策略设计和合成了八个配体,包括烷基化反应,酰胺偶联和Ugi多组分反应。所有配体均带有羧酸根基团,用于配合镧系元素(III)离子,以及由Tröger碱骨架本身或连接的苯甲酰胺组成的镧系元素(III)敏化单元。在发色配体的照射下,有效地产生了绿色ter(III)的发射,而euro(III)的发射可以忽略不计。发光敏化效率,表明对位取代模式比元取代更有效地形成具有较低Tb III /配体比的配位化合物。我们建议形成的物种是自组装的2:2或2:4的金属超分子结构。
Functionalized analogues of Tröger's base: scope and limitations of a general synthetic procedure and facile, predictable method for the separation of enantiomers
A major stumbling block in the applications of enantiomerically pure Tröger'sbase analogues is their poor availability. We have therefore developed a facile method for the enantioseparation of functionalized Tröger'sbase analogues possessing various substitution patterns. The systematic separation of a library comprising 36 representatives on the commercially available Whelk O1 chiral stationary

The synthesis of six new examples of 2,8-dinitro-substituted Troger'sbaseanalogues are reported, together with the first examples of 1,7-, 3,9- and 4,10-dinitro Troger'sbaseanalogues and the first example of a tetranitro Troger'sbase compound. Several of these dinitro compounds lack substituents at the 2- and 8-positions and therefore provide further examples of Troger'sbaseanalogues derived
Abstract Eleven different derivatives of Tröger’s base were synthesized and successfully resolved by (recycling) HPLC on chiral stationary (S,S)-Whelk-O1 or CHIRALPAK IA phase on a (semi-) preparative scale or synthesized in enantiomerically pure form. The absoluteconfiguration was determined by X-ray crystal structure analysis, comparison of the quantum chemically calculated circular dichroism spectra

structure of Troger's base bearing 2,2'-bipyridine and 2-pyridylmethanimine moieties have been synthesized. These ligands undergo diastereoselective self-assembly to dinuclear double-stranded D2d-symmetric helicates upon coordination to copper(I) and silver(I) ions as elucidated by NMR techniques and ESI mass spectrometric methods.
