A two-co-ordinated gold(I) loop [Au(dpdo)]ClO₄ [dpdo = 1,8-bis(diphenylphosphino)-3,6-dioxaoctane] as a luminescence light switch for substrate binding reactions

Abstract

Reaction of [Au(tht)Cl] (tht = tetrahydrothiophene) with dpdo [dpdo = 1,8-bis(diphenylphosphino)-3,6-dioxaoctane] afforded [Au(dpdo)]⁺ 1 which was isolated as a perchlorate salt; binding of a phosphine moiety to 1 in solution triggered a strong photoluminescence.
