Versatile, Extrudable and Luminescent Tripodal BTA-Terpyridine (tpy) Gel Cross-Linked with d- and f-Block Metal Ions.

The low molecular weight gelator (LMWG) 1 based on the tripodal benzene-1,3,5-tricarboxamide (BTA) motif, capped with terpyridine (tpy) units, was shown to form supramolecular gels with versatile functionalities such as self-healing, while the cross-linking of its fibers with d- and f-block metal ions led to modified photophysical properties, the obtained gels were additionally capable of extrusion.
