| Abstract(in English) | We investigated the absorption, photoluminescence (PL), and PL anisotropy spectra of a variety of poly(alkylarylsilylene)s in solution at room temperature and in thin film form at 20 K. The poly(alkylarylsilylene)s include poly(methyl-p-t-butylphenylsilylene) (1), poly(methylphenylsilylene) (2), poly(ethylphenylsilylene) (3), poly(n-pentylphenylsilylene) (4),poly(n-hexylphenylsilylene) (5) and poly(n-pentyl-m-tolylsilylene) (6). Although there was always a visible PL band from 1,2, and 3 in the visible region, there was almost no visible PL band with thin films of 4,5, and 6 in the room temperature to 20 K range. We ascribe the difference in the PL characteristics to the extended global shape with a spatially homogeneous local conformational structure in solution and in solid films. |
