Versatile precursors for multinuclear platinum(ii) alkynyl assembly—synthesis, structural characterization and electrochemical studies of luminescent platinum(ii) alkynyl complexes
Abstract
Newly synthesized diethynylcarbazole-bridged platinum(II) complex 3,6-{ClPt(PEt3)2CC}2-9-nBuCarb (nBuCarb =
CC6H4C
CH)]OTf were shown to serve as versatile precursors for the assembly of a novel luminescent tetranuclear platinum(II) alkynyl complex [3,6-{Pt(tBu3trpy)(C

C}2-9-nBuCarb](OTf)2. A divergent route can also be applied to synthesize the tetranuclear complex in three steps, involving the use of
