| Abstract |
Semiconducting polymers have attracted wide attention from fundamental science to industrial applications, which originates from their useful characteristics such as easy manufacture of thin-film devices and considerable charge-carrier conductivity. Since they are commonly used in electronic devices, one of the most important properties of semiconducting polymer films is their bandgap that affects the overall device performance. The bandgap of semiconducting polymers is mainly determined by well-conjugated π-electronic part of the polymer that may constitute the “chromophore”. However, other factors such as stereochemistry between the repeated units or arrangement of saturated aliphatic chain moiety often affect the bandgap as well, because they can modify the degree of aggregation of chromophores. In this work, we studied the effects of polymer structure and stereochemistry on the properties of thin films, especially on interfacial bandgap, using non-invasive optical spectroscopy. |
