Description

High Performance Photoinitiators for 3D Laser Lithography. To overcome key challenges of 3D printing on the micrometer scale, this projects develops next generation photoresists for 3D laser lithography. Based on a precision photophysical analysis approach, a blue print will be derived that creates the missing link between the chemical structure of photoinitators and their ability to print in two photon absorption processes. Based on this blueprint, high performance initiators will be synthesised and embedded into photoresists that break two barriers in contemporary 3D laser lithography: (i) Resists that decouple photopolymerisation processes from the printing process to eliminate volume shrinking during printing. (ii) Resists that allow to print 3D structures in the presence of living cells.. Scheme: Linkage Projects. Field: 3403 - Macromolecular and Materials Chemistry. Lead: Prof Christopher Barner-Kowollik
