Synthesis and supramolecular self-assembly of glutamic acid-based squaramides

open access: yesBeilstein Journal of Organic Chemistry, 2018
We describe the preparation and characterization of two new unsymmetrical squaramide-based organogelators. The synthesis of the compounds was carried out by subsequent amine condensations starting from dimethyl squarate.

Silver Dendritic Gels with Luminescence and Aggregation-Induced Emission Effect

open access: yesGels
This work reports on a novel family of silver metallogels based on discrete coordination complexes. Structurally, they consist of dendrimers containing a trinuclear silver metallacycle at the core, with the general formula [M(μ-pz)]3, and poly(benzyl ...
