抄録
A highly luminescent disubstituted polyacetylene, poly(1-phenyl-2-p-n-butylphenylacetylene) (PDPA-nBu), and its blend with a poorly luminescent monosubstituted polyacetylene, poly(1-o-trimethylsilylphenylacetylene) (PPA-oSiMe3), are studied by time-resolved photoluminescence (PL) spectroscopy. In pure PDPA-nBu, PL intensity at short wavelength decays faster than that at long wavelength, whereas PL spectra exhibit a dynamic Stokes shift to longer wavelengths with time. In blends of PDPAnBu/PPA-oSiMe3, only PL originating from PDPA-nBu is observed, without contribution from PPA-oSiMe3. The PL lifetime drastically decreases upon mixing a small amount of PPA-oSiMe3 in PDPA-nBu. The PL characteristics of pure PDPA-nBu and its blend with PPA-oSiMe3 are discussed in terms of lattice/vibrational relaxation of the excitonic state and exciton migration.

DCTERMS.abstract
A highly luminescent disubstituted polyacetylene, poly(1-phenyl-2-p-n-butylphenylacetylene) (PDPA-nBu), and its blend with a poorly luminescent monosubstituted polyacetylene, poly(1-o-trimethylsilylphenylacetylene) (PPA-oSiMe3), are studied by time-resolved photoluminescence (PL) spectroscopy. In pure PDPA-nBu, PL intensity at short wavelength decays faster than that at long wavelength, whereas PL spectra exhibit a dynamic Stokes shift to longer wavelengths with time. In blends of PDPAnBu/PPA-oSiMe3, only PL originating from PDPA-nBu is observed, without contribution from PPA-oSiMe3. The PL lifetime drastically decreases upon mixing a small amount of PPA-oSiMe3 in PDPA-nBu. The PL characteristics of pure PDPA-nBu and its blend with PPA-oSiMe3 are discussed in terms of lattice/vibrational relaxation of the excitonic state and exciton migration.
