Entwined dimer formation from self-complementary bis-acridiniums

pH controlled assembly of a self-complementary halogen-bonded dimer.

Phenols and their corresponding phenoxide anions can form halogen bonds with neutral iodotriazoles. The strength of these interactions depends critically on the protonation state of the oxygen atom - the interaction of the phenoxide anion is more than an order of magnitude stronger than the corresponding phenol. The assembly of a molecule bearing both an iodotriazole and a phenoxide anion into ...

Complementary face-to-face dimer formation from meso-aryl subporphyrins bearing a 2-carboxyphenyl group.

meso-Aryl-substituted subporphyrins bearing a 2-carboxyphenyl group were prepared and shown to form complementary face-to-face dimers upon azeotropic removal of methanol.

Entwined engrams

The nematode Caenorhabditis elegans displays a surprisingly sophisticated behavioral repertoire that includes the utilization of both associative and non-associative forms of learning. Elucidating the molecular basis of learning remains a fundamental, yet daunting, challenge of modern neuroscience. In Pereira and van der Kooy (ref. 2), we described the use of a two input-two output stimuli syst...

Stable supramolecular dimer of self-complementary benzo-18-crown-6 with a pendant protonated amino arm.

The novel 4'-(ammoniummethylene)benzo-18-crown-6 cation was synthesized as a hexafluorophosphate salt and found to exist as a cyclophane-like dimer in the solid state, gas phase and in acetonitrile solution.
