Summary: β ‐Cyclodextrin ( β ‐CD) pseudopolyrotaxanes containing poly(thiophene‐2,5‐diyl), PTh , or poly(3‐methylthiophene‐2,5‐diyl)s, P3MeTh s, as an axle were prepared. Structures of the pseudopolyrotaxanes and their inclusion behavior with β ‐CD were investigated. The UV‐vis measurements revealed that inclusion of P3MeTh s by β ‐CD depended on the flexibility of the main chain and their molecular weight.Formation of the inclusion complex of β ‐CD and PTh .
