A two-photon active chevron-shaped type I photoinitiator designed for 3D stereolithography

We present herein the properties of a highly reactive type I photoinitiator with significant 2PA cross-sections ( δ 720nm ∼ 90 GM). We demonstrate that this new type of photocleavable system exhibits very efficient two-photon polymerization abilities with performances amplified by more than two orde...

Description
Summary:We present herein the properties of a highly reactive type I photoinitiator with significant 2PA cross-sections ( δ 720nm ∼ 90 GM). We demonstrate that this new type of photocleavable system exhibits very efficient two-photon polymerization abilities with performances amplified by more than two orders of magnitude with regards to those of a commercially available type I photoinitiator (Lucirin TPO-L ) which is extensively employed for multiphoton 3D stereolithography. A highly reactive two-photon cleavable initiator with a chevron-shaped architecture has been designed which presents very promising performances for three-dimensional multiphoton fabrication.
