Single-molecule spectroscopy on a ladder-type conjugated polymer: electron-phonon coupling and spectral diffusion.

Abstract

We employ low-temperature single-molecule spectroscopy combined with pattern recognition techniques for data analysis on a methyl-substituted ladder-type poly(para-phenylene) (MeLPPP) to investigate the electron-phonon coupling to low-energy vibrational modes as well as the origin of the strong spectral diffusion processes observed for this conjugated… (More)
