  Rapid access to C ₃- and C _s-symmetric AAT organogelators via ring opening of a common benzotrifuranone precursor

  摘要：

  Presented is a rapid and general approach to functionalised 1-aza-adamantanetrione (AAT) donor-sigma-acceptor molecules from a phloroglucinol-derived trilactone, benzotrifuranone (BTF). Ten C3-symmetric AATs bearing diverse aryl amide substituents are accessed in two synthetic steps: (1) the exhaustive ring opening of BTF with aromatic amine nucleophiles (performed in up to 91% yield) and (2) cyclisation with hexamethylenetetramine (performed in up to 75% yield). Additionally, stepwise ring opening of BTF allows synthesis of phloroglucinol intermediates with two unique aryl amide substituents and ultimately Cs-symmetric AATs. Of the novel AATs prepared, three (including the Cs-symmetric hybrid) are effective gelators of chlorinated solvents (critical gelation concentration (CGC)=0.2-0.4 wt%) and one, with naphthyl substituents, forms translucent gels from aromatic solvents (CGC0.3 wt%). The combination of AATs with moderately electron-poor and electron-rich aromatic substituents results in functional complementarity and gelation at concentrations below what is required for the individual components. Electron microscopy of the gel morphologies shows high aspect ratio fibres underlying the gel network superstructures in most cases. Polarised optical microscopy has allowed imaging of representative native organogel phases, and reveals striking morphology differences between gels that also share different optical and/or thermal stability properties.

  Benzotrifuranone: Synthesis, Structure, and Access to Polycyclic Heteroaromatics

  摘要：

  Functionalized benzotrifurans can be accessed in one efficient acylation step from previously unreported benzotrifuranone. DFT calculations have confirmed the aromaticity of the heteroaromatic system and determined its electronic structure that is relevant to applications in materials and supramolecular chemistry.

  intramolecular hydrogen bonding (7MHB) arrangements involving phenolic hydroxyl group donors have been investigated through Cambridge Structural Database (CSD) and literature mining, and by the characterization of model compounds. The CSD reveals the numerous H-bond accepting functional groups that can participate in 7MHB when they are proximal to a phenolic OH, including alcohols, amides, amines, ethers, N-containing

  investigation of the first molecular multi-FRET system from the benzotrifuranone (BTF) scaffold. The step-conservative synthetic approach to the representative target exploits the sequential aminolysis reactivity of BTF, together with CuAAC, for installation of three optically complementary chromophores, naphthalene, pyrene, and coumarin (1). Studied in parallel are two sets of three single- and double-dye comparator
