Embodiment 1
[0198] Samples are depicted in the attached figures. 1A-1F were synthesized as follows: 8-10% by weight dye sample and 90-92% by weight polygorskite clay sample (Dish Technology) were ground in a mortar and pestle. A small sample of the milled mixture was placed in a laboratory notebook as a reference color for the milled starting material. Each mixture was placed in a Blue M oven at 170°C for 3 hours. After 3 hours, the sample was removed from the oven and the color change, if any, exhibited by the sample was noted. Do X-ray diffraction (XRD) spectrum (XRD) before and after heat treatment of each sample ( Figures 2A-2G ).
[0199] Figure 1A The color change of the reaction of anthrone group solvent dye and polygorskite before and after heating is shown. Solvent Blue 35 and Solvent Red 146 did not undergo a color change upon heating, remaining dark blue and dark red respectively, but did change within the XRD pattern. Solvent Red 169 changes from purple to deep red, whi...

The compound of formula (I) is wherein A is N, C, or S; the A-R5 bond is a single bond or a doublebond; R1 is H, -NH2, or -S-aryl; R2 is H or together with R3 form a fused bicyclic group; R3 is H, or together with R2 form a fused bicyclic group, or together with R4 and R5 form a fused tricyclic group; R4 is H, or together with R3 and R5 form a fused tricyclic group, or Formula (II); R5 is H, O, or together with R3and R4 form a fused tricyclic group; R6 is H, OH, -NH-alkyl, or -NH-aryl; R7 isH; R8 is H, -O-aryl, or halogen; and R9 is H, NH2, -NH-alkyl, NH-aryl, OH, or -S-aryl. Formula (III) is wherein B and D are each independently C, N, or S; Z is C; the B-R11 bond is a single bond or adouble bond; R11 is O, -NH, or together with R12 form a fused tricyclic group; R12comprises a fused bicyclic group, or together with R11 form a fused tricyclic group; the D-R13 bond and the Z-D bond are each independently a single bond or a double bond; R13 is O; and R14-R17 are each independently either H or halogen. Formula (IV) is wherein F is C or N; the E-F bond, the E-R25 bond, and the G-R27 bond are each independently either a single bond or a double bond; R25 is O or together with R26 and R27 form a fused bicyclic group; R26 is a substituted aryl group or together with R25 and R27 form a fused bicyclic group; R27 is O or together with R25 and R26 form a fused bicyclic group; and R28 is H or -NH2. A support is provided wherein the compound is complexed with the surface of the support.
