A new dinuclear rhodium(I) complex [Rh 2 (cod) 2 (imH) 2 im]PF 6 (I) has been synthesized and characterized. The complex is unstable in solution where it undergoes modifications leading to insoluble oligomers. However, it exhibits high catalytic activity towards polymerization of phenylacetylene (PPA) films can be obtained under mild reaction conditions. As‐grown PPA films are stable and soluble. Two different types of morphologies were found: one exhbits a cell‐like structure with microfibrils inside the cell and the other a dense enamel‐like smooth surface.
