Multiphase transition of supramolecular metallogels triggered by temperature.
We present a new family of supramolecular metallogels undergoing reversible multiphase transition triggered by temperature from amphiphilic alkynylplatinum(ii) complexes. Further investigation revealed that intermolecular PtPt and π-π stacking interactions facilitate such phase transitions upon increasing the temperature.
متن کاملSupramolecular metallogels with bulk self-healing properties prepared by in situ metal complexation.
In this feature article, we discuss a series of contributions dealing with the in situ fabrication of supramolecular metallogels (i.e. using low molecular weight ligands and metal ions) that show self-healing properties of the bulk gel phase after complete physical segregation. Most of the advances in this area have taken place during the last three years and are mainly represented by organogel...
متن کاملCross-linked supramolecular polymer metallogels constructed via a self-sorting strategy and their multiple stimulus-response behaviors.
Novel cross-linked supramolecular polymer metallogels were successfully constructed from four components via a self-sorting strategy, and feature interesting multiple stimulus-response behaviors under various external stimuli, including halide, base, and competitive guests.
متن کاملNear-infrared chiro-optical effects in metallogels.
A series of novel metallogelators containing near-IR nickel-bis(dithiolene) absorbers were rationally designed and synthesized. Robust gel networks are formed by right handed helical 1D-nanofibers which generate strong and remarkable chiro-optical effects in the near-infrared region.
متن کاملDifferentially-protected steroidal triamines; scaffolds with potential for medicinal, supramolecular, and combinatorial chemistry.
Cholic acid 2a has been converted into two new orthogonally-protected triamino scaffolds, 13 and 14. The synthesis proceeds via the bis-Boc-NH-substituted azide 10, for which an improved preparation is described. After removal of the Boc groups, the two axial amines are differentiated through a novel monoprotection employing 1-(2-nitrobenzenesulfonyloxy)-benzotriazole 29. Regioselectivity of > ...
