Triplet exciton generation and decay in a red polydiacetylene studied by femtosecond spectroscopy

Results from femtosecond/picosecond transient absorption spectra measurements in the near-infrared/visible spectral region of the red form of a soluble polycarbazolyldiacetylene in a polyethylene matrix are reported. Intrachain singlet and triplet excitons are identified by the different dynamics of...

Description
Summary:Results from femtosecond/picosecond transient absorption spectra measurements in the near-infrared/visible spectral region of the red form of a soluble polycarbazolyldiacetylene in a polyethylene matrix are reported. Intrachain singlet and triplet excitons are identified by the different dynamics of the photoinduced bands. The results are consistent with the ultrafast generation (
