Optical Anisotropy and Strong H-Aggregation of Poly(3-Alkylthiophene) in a Surface Monolayer

Slab optical waveguide absorption spectra reveal that surface segregated monolayers of a vertically oriented poly(3‐buthylthiophene) derivative have large optical anisotropy, and that confinement of the polymer chains in the isolated monolayer causes strong H‐aggregation.
