Abstract
A phenyltriazine compound has been used for the first time as a monomer in the construction of a hydrogel. This physically cross-linked soft material showed blue fluorescence when excited under UV-light. Polymer formation and intermolecular H-bonds arising from triazine moieties operate as aggregation-induced emission (AIE) mechanisms. The combination of soft materials and AIE properties expands the applications of these materials. As a proof of concept, two luminescent dyes have been incorporated into the hydrogel to produce a white-light-emitting material.

Abstract
In this contribution we describe a novel hydrogelator based on four guadiniumcarbonylpyrrole units in combination with aggregation-induced emission active aromatic thioethers which undergo self-assembly into fibrills in aqueous media as visible in AFM and TEM measurements. These fibrills are weakly luminescent and unable to induce gelation. Upon addition of malonic acid a cross-linking of the single fibres was detected leading to the formation of a highly emissive stable hydrogel. This gel responds to several external stimuli such as heat, shaking as well as pH changes.
