A new dinuclear rhodium(I) complex [Rh2(cod)2(imH)2im]PF6 (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 as compared with other rhodium-imidazole complexes. Free-standing polylphenylacetylene (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 exhibits a cell-like structure with microfibrils inside the cell and the other a dense enamel-like smooth surface.

Abstract
A new dinuclear rhodium(I) complex [Rh2(cod)2(imH)2im]PF6 (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 as compared with other rhodium-imidazole complexes. Free-standing polylphenylacetylene (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 exhibits a cell-like structure with microfibrils inside the cell and the other a dense enamel-like smooth surface.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
