Abstract

The synthesis, characterization, and quantitative electronic structure modeling of multi- photon absorption properties of a neat liquid L34 (4-propyl 4′-butyl diphenyl acetylene) are reported. The liquid is (linearly) transparent in the visible spectrum, but possesses large two- photon absorption (2PA) and 2PA-induced singlet and triplet excited-state absorption as measured by the Z-scan technique and non-linear transmission measurements using both ...
