  The new chiral ligand 4′-[6-(2,2′-diethoxy-1,1′-binaphthyl)]-2,2′:6′,2″-terpyridine (L1) was synthesized in three steps in 47% overall yield starting from 6,6′-dibromo-2,2′-diethoxy-1,1′-binaphthalene. L1 was quantitatively converted to 4′-[6-(2,2′-dihydroxy-1,1′-binaphthyl)]-2,2′:6′,2″-terpyridine (L2) by treatment with BBr3, while L2 was treated with tert-butyldimethylsilyl chloride to give to 4′-6-[2,2′-bis(tert-butyldimethylsiloxy)-1,1′-binaphthyl]}-2,2′:6′,2″-terpyridine (L3) in high yields. These new chiral terpyridine ligands L1–3 were coordinated to Ru(III) centers to generate Ru(L1–3)Cl3 which were then treated with the tetrakis(terpyridine) core in the presence of 4-ethylmorpholine to afford chiral Ru(terpy)22+ based metallodendrimers containing enantiopure 1,1′-bi-2-naphthyl units in their peripheries. These chiral metallodendrimers were characterized by NMR, ESI-MS, and cyclic voltammetry, while their photophysical properties were studied using UV-Vis, luminescence, and circular dichroism spectroscopies.

  新型的手性配体4′-[6-(2,2′-二乙氧基-1,1′-联萘)]-2,2′:6′,2′′-三联吡啶（L1）经过三步合成，总产率为47%，起始原料为6,6′-二溴-2,2′-二乙氧基-1,1′-联萘。L1通过与BBr3反应定量转化为4′-[6-(2,2′-二羟基-1,1′-联萘)]-2,2′:6′,2′′-三联吡啶（L2），而L2与叔丁基二甲基硅氯反应，高产率地生成4′-6-[2,2′-双(叔丁基二甲基硅氧基)-1,1′-联萘]}-2,2′:6′,2′′-三联吡啶（L3）。这些新型的手性三联吡啶配体L1–3与Ru(III)中心配位，生成Ru(L1–3)Cl3，随后在4-乙基吗啉存在下与四(三联吡啶)核心反应，得到基于手性Ru(terpy)22+的金属树状大分子，其周围含有手性纯的1,1′-双-2-萘基单元。这些手性金属树状大分子通过NMR、ESI-MS和循环伏安法进行表征，其光物理性质通过UV-Vis、发光和圆二色光谱学进行研究。

  Two new pentaerythritol-functionalised 2,2′:6′,2″-terpyridine (tpy) derivatives have been prepared. One contains four tpy metal-binding domains, whereas the other contains one tpy domain and three pendant CH2OH groups. The combination of these components with ruthenium-containing building blocks has allowed the specific and stepwise synthesis of tetranuclear and hexadecanuclear metallodendrimers.

  已经制备了两种新的季戊四醇官能化的2,2′:6′,2″-三联吡啶（tpy）衍生物。其中一种含有四个tpy金属结合域，而另一种则含有1个tpy域和3个CH2OH侧基。这些成分与含钌的构建模块相结合，可以逐步合成四核和十六核金属树状聚合物。
