A unique polyconjugated systems having longitudinal π-electron overlaps were synthesized. 8, 19-dihy-droxy- [2, 2] -metacyclophane was used as a raw material. The cyclophane was converted into two types of cyclophane polymers : One is a quinoid type polymer consisting of biphenoquinone skeleton with two methylene bridges. Another one is a phenol type polymer that contain 4, 4-dihydroxybiphenol skeleton. The structure of these polymers were mimicked that of organic charge transfer complex having longitudinal π-electron overlaps.<BR>The reaction mechanism converted oxidative dimer into phenol type polymer were discussed using D-substituted dihydroxymetacyclophane.<BR>Other examples of cyclophane polymer were also given.
