Abstract
We present absorption measurements in the visible (Vis) and infrared (IR) spectral range of Durham trans-polyacetylene (PA) with the film thickness varying between 4–240 nm. Photoinduced absorption (PIA) measurements support our finding of improved order in the samples with decreasing sample thickness. We conclude this from an apparent narrowing of the distribution of the effective conjugation lengths (lc,e f f) and a shift towards longer lc, e f f for films thinner than 60 nm. The results are interpreted by comparing tne experimental facts to theoretical simulations based on the experimentally determined dielectric function of Durham trans-PA.
