Abstract

An optical recording material and methods of making such material is provided. The material comprises of a dewar benzene monomer, with at least two cross-linkable groups, a sensitizer, a cross-linker, and an initiator. The material does not require a binder or a co-sensitizer. The material can be fabricated by an exceedingly easy technique that offers high photosensitivity, high diffraction efficiency, millimeter thickness, and high dynamic range.
