Research Abstract

The excited-state structure of crystalline thin films of π conjugated polymers has been studied, with a focus on the effect of interchain interaction. While there was no direct evidence indicating interchain interaction in crystalline thin films with relatively large interchain distances, it was found that the dipole forbidden states as well as dipole allowed ones are equally redshifted in crystalline thin films with a shorter interchain distance. In this work, the nature of the interchain interaction is investigated and its origin is also discussed.
