4. Boronic acid-modified alginate enables direct formation of injectable, self-healing and multistimuli-responsive hydrogels.

Author

Subjects
BORONIC acids, ALGINATES, HYDROGELS
Abstract

One-step functionalization of alginate with boronic acid groups allowed spontaneous formation of biocompatible hydrogels under basic conditions without additional complementary molecules or crosslinking agents. The dynamic nature of boronate ester bonds formed with vicinal diols present on alginate pyranose rings provided remarkable self-healing, injectable and multi-stimuli responsive properties to the material.

Abstract

Gold [Au(0)] nanoparticles immobilized into a stable covalent organic framework (COF) have been synthesized via the solution infiltration method. The as-synthesized Au(0)@TpPa-1 catalyst shows high recyclability and superior reactivity for nitrophenol reduction reaction than HAuCl4.3H2O. [ABSTRACT FROM AUTHOR]

8. Amino acid-based multiresponsive low-molecular weight metallohydrogels with load-bearing and rapid self-healing abilities.

Author

Saha, Subhadeep, Bachl, Jürgen, Kundu, Tanay, Díaz Díaz, David, and Banerjee, Rahul

Subjects
HYDROGELS, AMINO acids, MOLECULAR weights, LIGANDS (Chemistry), SALTS
Abstract

A multiresponsive metallohydrogel based on an amino acid-derived low molecular weight (LMW) ligand and a Zn(ii) salt was prepared. This hydrogel showed remarkable shape-persistent, self-standing, load-bearing and self-healing properties, which is uncommon in LMW hydrogels. [ABSTRACT FROM AUTHOR]

9. Modular synthesis of formamidines and their formation of stable organogelsElectronic supplementary information (ESI) available: Experimental details, expanded discussion and compound characterization. See http://www.rsc.org/suppdata/cc/b4/b406704e/

Author

Díaz, David D. and Finn, M. G.

Abstract

An improvement in the practical aspects of formamidine synthesis has resulted in the discovery of a class of compounds which produce organogels in protic solvents, presumably through intermolecular hydrogen bonding and π–π stacking interactions.
