Introduction of 84434-11-7 :

TPO-L is a photoinitiator for the 3D printing of resin that promotes two-photon induced polymerization. The two-photon absorption cross-section spectrum of Lucirin TPO-L shows a maximum of 1.2 GM at 610 nm. Despite its small two-photon absorption cross-section, Lucirin TPO-L exhibits high polymerization quantum yields[1][2][3]. In Vitro:Preparation for TPO-L solution:[1]
Lucirin TPO-L/ethanol solution with concentrations of 7×10−3 and 9×10−1 M.
TPO-L fpr 3D Printing of Resin:[2]
For printing, 50 g of Cubiflow with 1.18 wt % TPO-L as photoinitiator and 0.05 wt % UV-1995 as UV-Vis absorber were prepared. Curing was done with an intensity of 4 mW cm−2 and 40 s exposure per layer. The layer height was set to 50 µm. The specimens were oriented flat on the XY-plane and printed without support structures. One set was post-cured for 300 s in the UV flood curing system, and the other set was used as printed (green).
