Abstract: An organic molecular compound comprising a complex fluorene structure having either: wherein: X1, X2, X3, and X4 are individually the same or different and include a moiety containing at least one CH and one N; R1, R2, R3, and R4 are substituents each being individually hydrogen, or amino, or alkyl, or alkenyl, or alkynyl, or alkoxy of from 1 to 40 carbon atoms; aryl or substituted aryl of from 6 to 60 carbon atoms; or heteroaryl or substituted heteroaryl of from 4 to 60 carbons; or F, Cl, or Br; or a cyano group; or a nitro group; or R3, or R4 or both are groups that form fused aromatic or heteroaromatic rings; or R1 and R2 together form a cyclic ring having 3 to 20 carbon, nitrogen, sulfur or oxygen atoms; or R1 and R2 together form a double bond moiety.

Abstract: An imaging member, such as a negative-working printing plate or on-press cylinder, has an imaging layer comprised of a thermally sensitive compound and a photothermal conversion material. The thermally sensitive compound comprises a heat-activatable bisulfite adduct and can be a polymer or a small molecule compound. In the imaging member, the thermally sensitive compound reacts to provide increased hydrophobicity in areas exposed to energy that provides or generates heat. The imaging layer is considered “switchable” and can be used to provide a lithographic printing image without traditional alkaline wet processing.
