The Radiation Sensitivity of Select Metal Chelate Polymers: Mechanistic Changes at Higher Energies.

Abstract

Based on uranyl photochemistry in the visible/ultraviolet region, uranyl carboxylates are known to undergo CO2 evolution; however, with gamma radiation (cesium-137, 662 keV) a sizable number of uranyldicarboxylate polymers crosslink with high efficiency and without CO2 evolution. On the other hand several dicarboxylates with sulfur in the organic backbone exhibit very high scission efficiency. G values in excess of normal organic resists is related to the heavy atom content of these metal coordination polymers. Keywords: Radiation sensitive polymers, Uranyl polymers, Positive resists, Metal coordination polymers; Dioxouranium polymers, Negative resists, Metal coordination polymers.
