3D-Printing Multi-Component Multi-Domain Supramolecular Gels with Differential Conductivity.

We report the use of wet-spinning to 3D-print gels from low-molecular-weight gelators (LMWGs) based on the 1,3 : 2,4-dibenzylidenesorbitol (DBS) scaffold. Gel stripes assembled from DBS-CONHNH and DBS-COOH are printed, and their conductivities assessed. Printed gels based on DBS-CONHNH can be loaded with Au(III), which is reduced in situ to form embedded gold nanoparticles (AuNPs).
