Titanium(IV) Complexes Based on Tri­dentate N,N,O Ligands – Synthesis, Structure, and Thermal Decomposition

Abstract

Wet‐spun stimuli‐responsive composite fibers made of covalently crosslinked alginate with a high concentration of single‐walled carbon nanotubes (SWCNTs) are electroconductive and sensitive to humidity, pH, and ionic strength, due to pH‐tunable water absorbing properties of the covalently crosslinked alginate. The conductivity depends on the material swelling in humid atmosphere and aqueous solutions: the greater the swelling, the smaller is the electrical conductivity. The covalently crosslinked fibers reversibly deform during the swelling/shrinking. In the swollen state, the fibers are less conductive, while they return to the same level of conductivity after shrinking. This unique reversible change of electroconductivity of the SWCNT‐alginate fibers is due to the elastic deformation of the alginate network in the area of electrical contacts between SWCNT bundles arrested in the alginate matrix. Fibers of this kind can be used as a simple, robust, disposable, and biocompatible platform for electrotextiles, biosensors, and flexible electronics in biomedical and biotechnological applications.

Amino-Polyalcohol-Solvothermal Synthesis of Titanium-Oxo Clusters: From Ti6 to Ti19 with Structural Diversity

“…However, there are significantly fewer titanium amino alcohol complexes than those compounds of 3d, 3d–4f, and 4f metals . Furthermore, although the chelating amine of amino alcohol can increase the coordinative saturation of the metal ions, the so far reported titanium amino alcohol complexes still represent low nuclearity. − …”
