ConcepciónUnderstanding the Role of NHC Ditopic Ligand Substituents in the Molecular Diversity and Emissive Properties of Silver ComplexesART-2024-141171Silver bis(carbene) complexes featuring ditopic N-heterocyclic carbene (NHC) ligands have been synthesized which enable the assembly of supramolecular architectures via reaction with silver triflate. Through a systematic exploration of crystal structures and emissive properties, this study investigates the impact of the substituents on the NHC ditopic ligands [R-Im-2-Z-py], where R = Me, benzyl (Bz), or 2-naphthylmethyl (NaphCH2), and Z = H or Cl in the structural framework and emissive properties observed in the silver bis(carbene) or polynuclear species. Remarkably diverse structural motifs emerge in both of them, predominantly influenced by the choice of R wingtip and second by the Z substituent. Also the emissive quantum yield of the complexes is mostly governed by the selection of the R wingtip and further modulated by the Z substituent. Several of the mono and polynuclear complexes exhibit complex emissive profiles, including the observation of dual emission phenomena. Particularly noteworthy is the complex [Ag(NHC)]2]OTf (R = Bz, Z = Cl), which demonstrates an exceptionally intense single blue emission with a remarkable solid-state quantum yield (Φ) of 24%.2024http://zaguan.unizar.es/record/14770610.1021/acs.inorgchem.4c02940http://zaguan.unizar.es/record/147706oai:zaguan.unizar.es:147706info:eu-repo/grantAgreement/ES/DGA/E07-23Rinfo:eu-repo/grantAgreement/ES/MICINN AEI/PID2022-136861NB-I00info:eu-repo/grantAgreement/ES/MICINN/TED2021-130447B-I00Inorganic Chemistry 63, 45 (2024), 21699-21710byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
