WebThus, DETC is an attractive corresponding photoinitiator. We report on femtosecond pump–probe experiments on two different photoinitiators in solution. These two molecules have recently appeared as attractive candidates for far-field optical lithography based on stimulated-emission-depletion (STED) inspired approaches aiming at beating ... Webof the ratio between photoinitiator (DETC) and TEMPO-meth-acrylate was crucial. On one hand, the inclusion of nitroxide into the network forming the dynamic adaptive alkoxyamine bond is necessary to achieve the desired “living” features. On the other hand, the concentration of nitroxide is critical for successful printing.
