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 µm 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 ∼10−5 S cm−1.
2,9,16,23-四(2-吡咯-1-基烷氧基)酞菁,其中酞菁通过烷基间隔物连接到吡咯取代基,通过三个步骤制备,产量高。首次描述了与酞菁电隔离的电聚单体。在电位动态条件下或恒电位下,通过氧化电聚反应获得了厚度达5微米的吡咯取代酞菁薄膜。紫外/可见光谱显示聚合物中存在酞菁和多吡咯结构单元。充放电行为伴随着可逆的电致变色。聚合物薄膜表现出约10-5 S cm-1的特定电导率。
