Abstract: 
2,9,16,23-Tetrakis(2-pyrrol-1-ylalkoxy) phthalocyanines, in which the phthalocyanine is connected via an alkylene spacer to a pyrrole substituent, are prepared via three steps in good yields. For the first time monomers with groups for electropolymerisation electronically isolated from the phthalocyanine are described. Films of thickness up to 5 mm of these pyrrole substituted phthalocyanines were obtained by oxidative electropolymerisation under potentiodynamic conditions or at constant potential. UV/Vis spectra show the presence of phthalocyanine and polypyrrole structural units in the polymers. The charge-discharge behaviour is accompanied by a reversible electrochromic colour change. The polymer films exhibit specific electrical conductivities of similar to10(-5) S cm(-1).
