The design of organic molecules featuring large two-photon absorption cross sections that are of the form D-φ-D, A-φ-A, D-φ-A-φ-D, and A-φ-d-φ-A was reported. A nanocomposite approach was pursued to develop materials systems that allow for the laser writing of conductive metal features in a polymer matrix using one-photon or two-photon excitation. It was observed that completely free-form capability of two-photon lithography allows for the 3D fabrication of a wide range of periodic and non-periodic structures. It was shown that compounds with large twp-photon absorption cross sections and high photochemical reaction efficiencies have enabled the development of highly sensitive materials systems for two-photon 3D lithography.
