Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
119 words
A sulfonated rubrene represented by the formula (I): ##STR6## wherein each of the X, Y, Z, X', Y', and Z' substituents independently represents a member selected from the group consisting of hydrogen, C 1 -C 6 alkyl, chloro, fluoro, carboxy, C 1 -C 6 alkoxy, hydroxy, C 6 -C 12 aryloxy, and ##STR7## wherein M.sup.⊕ represents a member selected from the group consisting of ammonium, C 1 -C 6 alkylammonium, C 1 -C 6 dialkylammonium, C 1 -C 6 trialkylammonium, and alkali metal ions, and wherein the defined sulfonated rubrene contains the substituent ##STR8## in an amount at least sufficient to produce water-solubility of the sulfonated rubrene to the extent of 1×10 -4 moles per liter at ambient temperature.
Claim 2
Dependent Claim
119 words
A sulfonated rubrene represented by the formula (I): ##STR6## wherein each of the X, Y, Z, X', Y', and Z' substituents independently represents a member selected from the group consisting of hydrogen, C 1 -C 6 alkyl, chloro, fluoro, carboxy, C 1 -C 6 alkoxy, hydroxy, C 6 -C 12 aryloxy, and ##STR7## wherein M.sup.⊕ represents a member selected from the group consisting of ammonium, C 1 -C 6 alkylammonium, C 1 -C 6 dialkylammonium, C 1 -C 6 trialkylammonium, and alkali metal ions, and wherein the defined sulfonated rubrene contains the substituent ##STR8## in an amount at least sufficient to produce water-solubility of the sulfonated rubrene to the extent of 1×10 -4 moles per liter at ambient temperature.
Claim 3
Dependent Claim
20 words
The composition of claim 1 wherein three of the substituents are --SO 3 .sup.⊖ Na.sup.⊕ and the others are hydrogen.
Claim 4
Dependent Claim
