Ligand-exchange of TOPO-capped CdSe quantum dots with quinuclidines

, 2012
[[abstract]]A series of tertiary amine quinuclidine-capped cadmium selenide (Q-CdSe) quantum dots (QDs) of ~4 nm in diameter was successfully synthesized via ligand exchange process in which the original hydrophobic trioctylphosphine oxide (TOPO) ligand ...

Micro–Mesoporous Ferrierite: Strategies for Tuning the Accessibility of a Peculiar Zeolite

ChemCatChem, Volume 18, Issue 10, 27 May 2026.
The anisotropic structure of ferrierite (FER) zeolite makes challenging the increase of catalyst effectiveness by hierarchical porosity. The pore mouth location of the active sites for butene isomerization requires a fine balance between development of external surface and retention of shape selectivity.

Mechanochemical Tandem Reactions: A Sustainable and Direct Route to 1,2‐Di‐Functional Indolizines via In Situ Baylis–Hillman Reaction, Cyclocondensation, Electrophilic C–H Chalcogenocyanation

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
We report a sustainable, atom‐economic, step‐economic approach for the organocatalytic construction and metal‐free C–H functionalization of indolizines by solid‐phase tandem mechanochemistry (E‐factor ∼4.0, eco‐score >70). Herein, we report a sustainable, metal‐free tandem mechanochemical strategy for the construction and C–H chalcogenocyanation of ...

Antimicrobial activity of a quinuclidine-based FtsZ inhibitor and its synergistic potential with £]-lactam antibiotics

, 2015
Filamenting temperature-sensitive mutant Z (FtsZ) is an essential cell division protein that cooperates in the formation of the cytokinetic Z-ring in most bacteria and has thus been recognized as a promising antimicrobial drug target.
