The chemical vapor deposition polymerization (CVDP) of alpha,alpha'-dichloro-p-xylene on the (0 0 1) plane of silicon wafer surface followed by thermal dehydrochlorination produced PPV nanofilms in which the polymer chains are found to be in highly ordered morphology. The same CVDP polymerization of alpha,alpha'-dichloro-p-xylene on the quartz surface, however, produced disordered polymer chains. The morphology and chain orientations were studied by X-ray diffractometry and polarized UV-Vis absorption and polarizesd photoluminescence spectroscopies. The angle dependence of IR refractive absorption spectra of the PPV films also were studied.
