Two-photon absorption in five-membered heteroaromatic oligomers

• Structure-to-property relations for the two-photon absorption intensities of oligothiophenes, oligopyrroles, and oligofurans have been studied using ab initio response theory. Power law dependences of the two-photon absorption intensities with respect to the length of the oligomers have been revealed, and localization lengths at which the intensities are completely dominated by one single state are found.
