Conejo Rodríguez, Verónica Peñas de Frutos, Marconi Nicolás Espinet Rubio, Pablo 2019-10-04T11:16:06Z 2019-10-04T11:16:06Z 2019 Dalton Transactions, 2019, vol. 48, n. 28. p. 10412-10416 1477-9234 http://uvadoc.uva.es/handle/10324/38372 10.1039/C9DT01618J Crystallographic and DFT examination of the metalloligands [AuAr(CNPy-4)] (Ar = C6F5 (1), C6F3Cl2-3,5 (2)) and their silver complexes [Ag[AuAr(CNPy-4)]2](BF4) (3 and 4) support that the marked luminescence red-shifts observed on moving from 1 to 2, from 1,2 to 3,4, or upon grinding, are not caused by electronic differences (either by changing the aryls C6F5/C6F3Cl2, or by N coordination to silver), nor by non-existent Au···Ag interactions. They are always due to structural changes disturbing stronger π-π stackings in order to allow for shorter Au···Au interactions. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ © 2019 Royal Society of Chemistry Attribution-NonCommercial-NoDerivatives 4.0 Internacional Gold Oro 4-Pyridylisocyanide Gold(I) and Gold(I)-plus-Silver(I) Luminescent and Mechanochromic Materials: The Silver Role info:eu-repo/semantics/article
