Irᴵᴵᴵ as a Strategy for Preorganization in H-Bonded Motifs

Here we present the synthesis and characterisation of four hydrogen bonded systems based on thiourea derivatives. These motifs are considered to be stable and desirable for supramolecular hydrogen-bonded functional materials. Interpretation of the structural design of thiourea based ligand and its incorporation into metal complexes can contribute to the understanding of preorganised self-assembly and open new pathways in design of novel soft materials. This work contributes to the unexplored library of hydrogen bonded metal complexes based on iridium. Further we examined the photoluminescence of the system of general formula [Ir(C^N)2(N^S)] and the effect of hydrogen bonding on the emission properties when combined with different n-heteroacenes.
