Photochemical Fragmentation of Irgacure PAG 103
Posted on 2019-11-12 - 19:06
Photoisomerization
of Irgacure PAG 103 followed by photocyclization
and fragmentation leads to three tricyclic thieno[2,3-b]quinoline-4-carbonitrile heterocyclic compounds. The release of
acid which can catalyze polymer resist modifications is indicated
by the low pH of an aqueous extract. These reactions are discussed
in view of possible mechanisms and how these might influence future
design strategies.
