Abstract | A series of novel polymers containing a bis-silicon-bridged p-terphenyl skeleton in the main chain is synthesized using hydrosilylation reactions with 6,12-dihydro-6,12-dimethyl-6,12-disilaindeno[1,2-b]fluorene (2) as the key monomer. Their photophysical and thermal properties are investigated and compared with those of the related monomer and model compounds. All polymers show an improved thermal stability with respect to the small molecules. In dilute solutions, the polymers constructed with alternate bis-silicon-bridged p-terphenyl and saturated unit show constant emission maximum wavelengths and fluorescence quantum yields, comparable to those of monomer 2, while the polymer having an unsaturated linkage between the bis-silicon-bridged p-terphenyl units exhibits a low fluorescence quantum yield with a red-shifted emission maximum wavelength. |
