Dye complexes and use thereof in imaging members and methods

An imaging method comprising the steps of:

• (a) providing an imaging member comprising an image-forming layer comprising a compound represented by the formula (I)
• wherein:
• R1, R2, R3, R4, R5, and R7 are each independently selected from the group consisting of:
• hydrogen, alkyl, substituted alkyl, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, heterocycloalkyl, substituted heterocycloalkyl, substituted carbonyl, acylamino, halogen, nitro, nitrilo, sulfonyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, oxygen, substituted oxygen, nitrogen, substituted nitrogen, sulfur and substituted sulfur;
• R6 is selected from the group consisting of:
• halogen, oxygen, substituted oxygen, nitrogen, substituted nitrogen, sulfur and substituted sulfur;
• R8, R9, R10 and R11 are each independently absent or selected from the group consisting of:
• hydrogen, alkyl, substituted alkyl, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, heterocycloalkyl, substituted heterocycloalkyl, substituted carbonyl, acylamino, halogen, nitro, nitrilo, sulfonyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, oxygen, substituted oxygen, nitrogen, substituted nitrogen, sulfur and substituted sulfur;
• X1 is selected from the group consisting of:
• carbonyl, methylene, substituted methylene, and sulfonyl;
• X2 is selected from the group consisting of:
• oxygen, nitrogen, or substituted nitrogen;
• X3 is selected from the group consisting of:
• oxygen, sulfur, nitrogen and substituted nitrogen;
• X4 is carbon or nitrogen;
• and
• A is a hydrogen-bond accepting group;
• said compound being in the crystalline form;
• and
• (b) converting at least a portion of said compound to an amorphous form in an imagewise pattern whereby an image is formed.
