Coordination polymers (CPs) exhibiting two-photon absorption (2PA) properties are of high interest for photophysically relevant applications. We design, implement, and employ an experiment to measure two-photon excitation spectra of pillar-layered CPs with nonlinear Fourier-transform spectroscopy. It is based on 10 fs pulses generated in a noncollinear optical parametric amplifier and a common-path birefringent interferometer. The comparison shows a significant difference for the 2PA cross-sections of the materials, improving it by incorporating the pillar.
