The two-photon absorption (TPA) cross-sections of series molecules with multi-branched structures was analyzed using ab initio response theory. The electronic coupling between the different arms of multi-branched molecules was found not very efficient for increasing the TPA cross-sections. In the case of two-dimensional charge-transfer cumulene-containing aromatic molecules, the TPA cross-section was drastically enhanced by increasing the dimensionality of the charge-transfer network. The vibronic coupling, was strong in multi-branched structures, which can result in an enhancement of the TPA cross-section.
