A new phthalocyanine–ferrocene conjugated dyad

The synthesis and optical properties of a new phthalocyanine–ferrocene conjugated dyad are reported. Using a Pd(0)-catalysed cross-coupling reaction, an unsymmetrical substituted metallophthalocyanine linked to a ferrocene subunit by an arylene–alkynylene spacer has been prepared. The electronic properties of this linearly π-conjugated compound and related ones were investigated by UV–visible spectroscopy.
