We describe the synthesis of new rigid rod polymers possessing a backbone of silicon phthalo‐cyanine units and stiff 4,4′‐dioxybiphenyl or 2,6‐dioxynaphthalene spacers. These modified phthalocyaninato‐polysiloxane derivatives are characterised by mass, absorption and 13 C‐CPMAS spectroscopies, differential scanning calorimetry and X‐ray powder diffractometry. UV/VIS spectra show only slight differences to the corresponding phthalocyanine monomers, which indicates the absence of excited state interactions between the chromophores within the polymer backbone.
