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%. info:eu-repo/grantAgreement/ES/DGA/E07-23R info:eu-repo/grantAgreement/ES/MICINN AEI/PID2022-136861NB-I00 info:eu-repo/grantAgreement/ES/MICINN/TED2021-130447B-I00 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 4.7 2024 CHEMISTRY, INORGANIC & NUCLEAR 6 / 43 = 0.14 2024 Q1 T1 0.958 2024 Chemistry (miscellaneous) 2024 Q1 Physical and Theoretical Chemistry 2024 Q1 Inorganic Chemistry 2024 Q1 7.4 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Crespo, Olga Universidad de Zaragoza (orcid)0000-0001-9522-5840 Gimeno, M.
