“…[DCA] − has a boomerang-like structure, with a permanent dipole and varied resonance structures, being often used as a bridge ligand to form cross-linked and organized structures. [ 35 , 36 ] So, physical crosslinking in [DCA] − ionomaterials likely results from a combination of ionic and electrostatic interactions, dipole–dipole (for example with Gly) and hydrogen bonds with hydrogen bond donor groups in gelatin. [ 37 ] Taken together, the properties of dicyanamide anion [DCA] − promote physical cross-linking between gelatin chains and yield mechanically robust ionogels.…”

Relative humidity is simultaneously a sensing target and a contaminant in gas and volatile organic compound (VOC) sensing systems, where strategies to control humidity interference are required. An unmet challenge is the creation of gas‐sensitive materials where the response to humidity is controlled by the material itself. Here, humidity effects are controlled through the design of gelatin formulations in ionic liquids without and with liquid crystals as electrical and optical sensors, respectively. In this design, the anions [DCA]− and [Cl]− of room temperature ionic liquids from the 1‐butyl‐3‐methylimidazolium family tailor the response to humidity and, subsequently, sensing of VOCs in dry and humid conditions. Due to the combined effect of the materials formulations and sensing mechanisms, changing the anion from [DCA]− to the much more hygroscopic [Cl]−, leads to stronger electrical responses and much weaker optical responses to humidity. Thus, either humidity sensors or humidity‐tolerant VOC sensors that do not require sample preconditioning or signal processing to correct humidity impact are obtained. With the wide spread of 3D‐ and 4D‐printing and intelligent devices, the monitoring and tuning of humidity in sustainable biobased materials offers excellent opportunities in e‐nose sensing arrays and wearable devices compatible with operation at room conditions.

“…Despite the fact that isostructural crystals are very similar in packing arrangement, they may have different properties. Thus, some coordination compounds exhibit difference in their thermal stability, 14,15 photoluminescent and magnetic properties, [15][16][17][18][19] heterogeneous catalytic and biological activity, 15,20,21 which, apparently, are most affected by the central metal ion.…”
