Abstract:

Derivatized malachite green leuco dyes for use in radio-chromic systems are described. The dyes have the following structure:in which Ar is a substituted phenyl or thiophene ring in which at least one substitution of the Ar ring is not ortho to the bond between the ring and the linking carbon, and in which R, R, R, and Rare independently selected from methyl, alkyl, or alkyl halide. The systems include the dyes in conjunction with an activator, e.g., a halogenated activator, and a carrier, e.g., a fluid carrier or an encapsulating polymeric matrix.

Abstract:

The present disclosure is directed to a low temperature method of preparing graphene. The method comprises applying a graphene oxide to a substrate and treating the graphene oxide on the substrate using photoreduction to reduce and stitch the graphene oxide to graphene. The present disclosure is also directed to graphene produced according to the aforementioned method.
