  Donor–acceptor interaction-mediated arrangement of hydrogen bonded dimers

  摘要：

  The donor-acceptor interaction-driven supramolecular arrangement of a new series of quadruply hydrogen-bonded homo- and heterodimers have been investigated in chloroform with H-1 NMR and UV-Vis spectroscopy. Two kinds of structurally complementary monomers have been prepared. Monomers 3 and 4 are incorporated with one ureidopyrimidone unit and one electron deficient pyromellitic diimide (PDI) or naphthalene diimide (NDI) unit, respectively, monomers 5 and 6 are incorporated with two ureidopyrimidone units and one PDI or NDI unit, respectively, whereas monomers 7 and 8 consist of one electron rich bis-p-phenylene[34]crown-10 unit and one or two 2,7-diamido-1,6-naphthyridine units, respectively. Compounds 3 and 4 exist exclusively as homodimers, respectively. Adding 1 equiv. of 7 to the solution of 3.3 and 4.4 induced them to partially or fully dissociate to produce heterodimers 3.7 and 4.7 due to intermolecular donor-acceptor interaction and the formation of a new binding mode between the ureidopyrimidone of 3 or 4 and the 2,7-diamido-1,6-naphthyridine unit of 7. Both 5 and 6 exist as cyclic monomer and dimer in chloroform. Adding 1 equiv. of 8 to the solution of 5 or 6 in chloroform caused all the cyclic dimer and most of the cyclic monomer to de-cyclize to form new heterodimers 5.8 and 6.8, respectively. H-1 NMR and UV-vis study revealed that heterodimer 5.8 has a structure in which the PDI of 5 is not threaded through the cavity of the bis-p-phenylene [34] crown-10 unit of 8. In contrast, in addition to the heterodimer similar to 5.8, about 40% of heterodimer 6.8 is generated, in which the PDI of 6 is threaded through the cavity of the bis-p-phenylene[3]crown-10 unit of 8 due to the increased donor-acceptor interaction between NDI and bis-p-phenylene [34] crown-10. Steric hindrance and mismatching of the hydrogen bonding moiety play important roles in the arrangement of the new homo- and heterodimers. (C) 2004 Elsevier Ltd. All rights reserved.

  供体-受体相互作用驱动四氢键合氢二聚体的选择性重排。

  摘要：

  通过引入额外的供体-受体相互作用，已开发出一种通用方法来控制梅耶尔的AADD四重氢键均二聚体的选择性重排。因此，在其中一种供体组装单体1中，其中富电子的双（对亚苯基）-34-crown-10部分与氢键合部分连接，而在两种供体组装单体2和3中，合成并表征了分别结合有电子缺陷的均苯四甲酸二酰亚胺或萘二酰亚胺基团。1H NMR和2D-NOESY研究表明，所有这些化合物均以稳定的均二聚体形式存在于氯仿中。在氯仿中混合1当量1和1当量2导致形成异二聚体1.2，产率约为60％，由于1的双（对亚苯基）-34-crown-10部分与2的均苯四甲二酰亚胺基团之间发生了静电相互作用，因此通过混合1当量的1可以实现选择性形成异二聚体1.3（> 97％）在氯仿中具有3当量的1当量，这导致1的双（对亚苯基）-[34] crown-10部分与3的萘二酰亚胺基团之间的静电相互作用增强。异二聚体1.2和1.3的结构具有通过1

  This paper describes the self-assembly of a new series of heterotrimers in chloroform-d by utilizing the cooperative interaction of hydrogen bonding and donor-acceptor interaction. Compounds 1 and 11, in which an 2-ureido-4[1H]-pyrimidinone unit is connected to 34-crown-10 or 36-crown-10, were used as donor monomer, and 2 and 19, in which an 2-ureido-4[1H]-pyrimidinone unit is connected to NDI, were used as acceptor monomer, while linear compound 4, which contains two diamido-1,8-naphthyridines, was used as template. A large tri-p-(t-butyl)phenylmethoxyl group was introduced to 19 in order to compare its assembling behavior with that of 2. Mixing 4 with dimer 1 (.) 2 caused 1 (.) 2 to fully decompose and to afford 55% of 'in-in'-oriented heterotrimer 1 (.) 4 (.) 2. Adding 4 to the solution of 2 (.) 11 or 11 (.) 19 in chloroform-d also led to full dissociation of the dimers. However, in these systems the 'in-in'-arranged heterotrimer 2 (.) 4 (.) 11 or 11 (.) 4 (.) 19 could be produced exclusively. (c) 2005 Elsevier Ltd. All rights reserved.
