Nucleobases are known as suitable builders of porous materials not only due to their high number of heteroatoms leading to different coordination modes, but also because they establish strong and predictable supramolecular interactions. In this contribution, nucleobases (adenine and guanine), functionalized nucleobases (9-methyladenine) and nucleobase derivatives (6-chloropurine) have been evaluated as ligands for the construction of metal–nucleobase building blocks which can afford supramolecular porous materials, analyzing in detail the requirements that these entities must fulfill and pointing out the relevance of accomplishing the suggested requisites. More concisely, we have evaluated a paddle-wheel shaped dimeric entity, [Cu2(μ-Hade)4Cl2]Cl2·8H2O (1) (where Hade: adenine), a trimeric unit, [Co3(μ-Hade)2(μ-Cl)4Cl2(H2O)4]·2H2O (2), a dimeric entity, [Cu2(Hgua)2(H2gua)2(μ-Cl)2Cl2(H2O)][CuCl4] (3) (where Hgua: guanine, H2gua: guaninium), a monomeric unit with 9-methyladenine as the pendant ligand, [Co(9-Meade)2(H2O)4]Cl2·2H2O (4), zigzag chains, [Cu2(μ-CH3COO)4(μ-9-Meade)]n·nCH3OH (5), and a monomeric unit with 6-chloropurinato ligands, [Co(6-Clpur)2(H2O)4]·4H2O (6).

为获得基于金属-核碱基实体的超分子材料的要求提供证据

核糖核酸酶被称为多孔材料的合适助洗剂,不仅因为它们的杂原子数量众多导致不同的配位模式,而且还因为它们建立了强大且可预测的超分子相互作用。在这一贡献中,已评估了核碱基(腺嘌呤和鸟嘌呤),功能化的核碱基(9-甲基腺嘌呤)和核碱基衍生物(6-氯嘌呤)作为构建金属-核碱基结构单元的配体,这些结构单元可提供超分子多孔材料,详细分析这些实体必须满足的要求,并指出完成建议的条件的相关性。更简而言之,我们评估了桨轮状的二聚体[Cu 2(μ-Hade)4 Cl 2 ] Cl2 ·8H 2 O( 1)(其中Hade:腺嘌呤),三聚体,[Co 3(μ-Hade) 2(μ-Cl) 4 Cl 2(H 2 O) 4 ]·2H 2 O( 2) ,一种二聚体,[Cu 2(Hgua) 2(H 2 gua) 2(μ-Cl) 2 Cl 2(H 2 O)] [CuCl 4 ]( 3)(其中Hgua:鸟嘌呤,H 2 gua:胍),以9-甲基腺嘌呤为侧基的单体单元[Co(9-Meade) 2(H 2O)4 ]氯2 ·2H 2 O(4),锯齿链,[铜2(μ-CH 3 COO)4(μ-9-米德)] ñ · Ñ CH 3 OH(5),以及单体单元具有6-氯嘌呤的配体,[Co(6-Clpur)2(H 2 O)4 ]·4H 2 O(6)。
