Self-assembly of 1- and 2-Dimensional Multicompartmental Arrays via the 2-Aminopyrimidine H-Bonding Motif and Selective Guest Inclusion
Abstract The H-bond mediated self-assembly of aminopyrimidine substituted anthracene derivatives 4 and 5, respectively, generate 1- and 2-dimensional multicompartmental arrays in the solid state as revealed by X-ray crystallographic analysis. The derived ‘pigeon-hole’ lattice is defined by syn-coplanar positioning of anthracene moieties at a distance of ca. 7 A, allowing the formation of selective clathrate-type inclusion entities with guests of appropriate shape and size, in particular phenazine, which presents both structural and interactional complementarity. These data provide insight into the interplay of the different structural and interactional features of the molecular components t…
Mixed-Valence, Mixed-Spin-State, and Heterometallic [2×2] Grid-type Arrays Based on Heteroditopic Hydrazone Ligands: Synthesis and Electrochemical Features
Une famille de complexes heterometalliques [M 1 2 M 2 2 (L - ) 4 ] n + du type grille [2×2] 1-9 a ete preparee. Les trois approches synthetiques multietapes des ligands hydrazone heteroditopiques A-C possedent chacune des caracteristiques regio-, redox-, enantio-selectives. Ces ligands possedent un groupement NH ionisable et un groupement hydrazone non-ionisable NMe, qui permettent un controle des proprietes redox du metal complexe en fonction de la charge de la cavite coordinante. Les substituants 2-pyrimidine (R) et 6-pyridine (R') influencent de maniere significative la geometrie des complexes formes ainsi que leurs proprietes electrochimiques et magnetiques. Les etudes par spectroscopie…
