  不寻常的大分子结构：树枝状聚酯和新型嵌段共聚物的趋同生长方法

  摘要：

  描述了树枝状聚酯的通用方法及其在制备两种不同类型的新型大分子结构中的用途，代表树枝状嵌段共聚物。为合成树枝状聚酯而开发的化学过程涉及通过使用二环己基碳二亚胺 (DCC) 和 4-(二甲氨基) 对甲苯磺酸吡啶 (DPTS) 的酯化步骤生成代生长，然后通过用锌去除其三氯乙酯基团来激活焦点在醋酸中。然后通过围绕中央多功能核以径向或同心方式受控放置不同的醚和酯化学物质来获得不寻常的球状嵌段结构。所以，树枝状链段-嵌段共聚物是通过将结合了聚酯和聚醚化学的径向交替树枝状链段连接到多官能核上而获得的。类似地，在最终偶联到核心部分的树枝状片段的制备中，通过醚和酯连接的层的同心交替获得树枝状层嵌段。用于制备醚连接片段的单体单元是 3,5-二羟基苯甲醇，而 3,5-二羟基苯甲酸 2,2,2-三氯乙酯用于酯连接片段。通过 NMR 光谱法和尺寸排阻色谱法对新嵌段共聚物的分析表明它们是纯的和单分散的。在它们链端的性质没有很大差异的情况下，

  Aryl polyester dendrimers and dendrons have been prepared by using ‘branched monomer strategies’, in which the surface and the focal point of the multi-branched monomer have been protected with two different kinds of protective group. The protective group for the focal point was stable during deprotection of the surface. Different wedges could be attached to the multi-branched monomers to form large dendrons whilst active dendrons could be attached to different cores to form various dendrimers with different wedges and different cores.

  已经通过“分支单体策略”制备了芳香聚酯树枝状高分子和树枝。该策略中，多分支单体的表面和焦点使用两种不同的保护基团进行保护。在去保护表面时，焦点的保护基团是稳定的。可以将不同的楔形结构连接到多分支单体上，以形成大型树枝状高分子，同时活性树枝可以连接到不同的核心，以形成具有不同楔形结构和不同核心的各种树枝状高分子。

  Five paddlewheel-shaped dicopper molecules, 1, 2a, 2b, 3 and 4, were synthesized from the reaction of copper acetate and different generations of Frechet-type dendrons (HG1-HG4). All compounds showed diagnostic bands in their FTIR spectra for the coordinated carboxylate groups with separations of COasym and COsym lower than 200 cm(-1) suggesting the formation of dimers. A broad absorbance band centered at 700, 695, 695 and 693 nm was observed for compounds 1-4 respectively, which is ascribed to the d-d charge-transfer in Cu(II) complexes. A LMCT absorption was observed near 304, 290, 298 and 294 nm for compounds 1-4 respectively. Magnetic susceptibility measurements for 1, 2a and 3 at 1.53, 1.53 and 1.7 respectively in the solid state at 293 K are also suggestive of a dimeric arrangement. The structures of HG2, 1, 2a, and 2b were characterized unambiguously with single crystal X-ray diffraction. Three molecules constituted the asymmetric unit of HG2 in the monoclinic space group P2(1)/n and resulted in dimers formed via intermolecular carboxylic acid-type hydrogen bonds. Compounds 1, 2a, and 2b contain centrosymmetric paddlewheel-shaped dinuclear copper molecules bridged by four carboxylate groups in syn, syn arrangements. The copper centers in compounds 1, 2a, and 2b are all coordinated by four carboxylate O atoms in a square pyramidal geometry and the ligands on the apical positions are disordered and occupied by either water, THF, pyridine or methanol molecules. In 1, all the hydroxyl O atoms are involved in hydrogen bonding, which results in the formation of a 3D network. pi-pi stacking interactions involving phenyl rings were observed in the crystal structures of HG2, 2a and 2b.
