  "abstract": "Here, we report the ability of spiropyrans to initiate two-photon polymerization (TPP) for the first time in the literature.The comparison and synergies between the spiropyran photochromic molecule of interest, namely 6nitro-BIPS, and well-known photoinitiators of radical photopolymerization have been studied.The spiropyran (SPy) molecule can initiate TPP in the presence of trifunctional acrylic monomers and create true 3D structures.The comparison with Irgacure 819, a well-known Type-I photoinitiator, shows that SPy has a comparable capability for TPP.In addition, the combination of SPy with methyl diethanolamine increased the reactivity of both one-and two-photon polymerizations.In the last section, we discuss which SPy isomer is the active photochromic species capable of generating radicals for initiating two-photon polymerization.",
