Benzobisimidazole Cruciform Fluorophores

A series of 11 cross-conjugated cruciform fluorophores based on a benzobisimidazole nucleus has been synthesized and characterized. Like in their previously reported benzobisoxazole counterparts, the HOMOs of these new fluorophores are localized along the vertical bisethynylbenzene axes, while their LUMOs remain relatively delocalized across the molecule, except in cruciforms substituted with electron-withdrawing groups along the vertical axis. Benzobisimidazole cruciforms exhibit a pronounced response to deprotonation in their UV/vis absorption and emission spectra, but their response to protonation is significantly attenuated.

A Porous and Solution-Processable Molecular Crystal Stable at 200 °c: The Surprising Donor-Acceptor Impact

We report a curious porous molecular crystal that is devoid of the common traits of related systems. Namely, the molecule does not rely on directional hydrogen bonds to enforce open packing, and it offers neither large concave faces (i.e., high internal f

Six butadiyne monomers with (dimethylamino)phenyl and N-substituted urethane substituents were synthesized and their crystal structures and solid-state polymerization were investigated. In five of the six monomers, directions of the butadiyne stacking and

(Five urethane derivatives of 8-[4-(dimethylamino)phenyl]octa-5,7-diyn-1-ol were synthesized. They could be polymerized in the solid state to give conjugated backbones although structural regularity seemed to be not so high. Formability of chargetransfer

Azides and acetylenes are bio-orthogonal functional groups that can be readily coupled using copper(I)- or ruthenium(II)- catalyzed 1,3-dipolar cycloaddition reactions. Using non-fluorescent aromatic azides and aromatic acetylenes, covering a range of electron rich and poor building blocks, the Huisgen cycloaddition afford 1,4-disubstituted or 1,5-disubstituted 1,2,3-triazoles. Using a combinatorial approach by running reaction in parallel in polypropylene 96-well plates we discovered several new fluorescent 1,2,3-triazoles scaffolds. These compounds show diverse interactions with biomolecules that could find applications in biology in, for example, fluorescence microscopy or biomolecule quantification.
Cobalt-Catalyzed Hydroalkynylation of Vinylaziridines

, p. 2578 - 2585 (2021/03/18)
Transition metal-catalyzed hydroalkynylation reactions are efficient transformations allowing the straightforward formation of functionalized alkynes. Therein, we disclose the cobalt-catalyzed hydroalkynylation of vinylaziridines giving rise to both linea
