TEN POLYTORSIONAL-AMIDE-INDUCED HELICAL-BASED COORDINATION POLYMERS WITH DIFUNCTIONAL ELECTROCHEMICAL ACTIVITIES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), gio 14 gennaio 2021 To investigate the synergistic coordination ability of a polytorsional-amide ligand to construct new coordination polymers (CPs), N,N′-bis(4-methylpyridin-4-yl)-1,4-naphthalenediamide (L) was selected as the main ligand. Ni2+ and Cu2+ with electrochemical activity and different carboxylates [2-nitrobenzoic acid (2-HNBA), 4-nitrobenzoic acid (4-HNBA), p-toluic acid......

SUPRAMOLECULAR ISOMERISM BETWEEN CYCLODIMERIC AND SINUSOIDAL 1D COORDINATION POLYMERS: COMPETITION OF TUNABLE ARGENTOPHILIC VS ELECTROSTATIC INTERACTIONS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), ven 08 gennaio 2021 Systematic supramolecular isomerism between metallacyclodimeric species and sinusoidal 1D coordination polymers was observed. Slow diffusion of AgX (X– = NO3–, BF4–, ClO4–, and PF6–) with 1,3-bis(dimethyl(pyridin-4-yl)silyl)propane afforded 28-membered metallacyclodimers [AgL]2(X)2 with argentophilic, electrostatic, and π-π interaction that are very sensitive to......
