Abstract The [Fc [BOND] bis {Zn II (TACN)(Py)}] complex, comprising two Zn II (TACN) ligands (Fc= ferrocene; Py= pyrene; TACN= 1, 4, 7-triazacyclononane) bearing fluorescent pyrene chromophores linked by an electrochemically active ferrocene molecule has been synthesised in high yield through a multistep procedure. In the absence of the polyphosphate guest molecules, very weak excimer emission was observed, indicating ...
