Abstract

A conductive polymer material can exhibit good heat resistance and good moisture resistance, in which the conductive polymer comprises as a dopant at least one of aromatic sulfonic acid derivatives represented by general formula 1: wherein at least one of R 1 to R 6 represents a sulfonic acid group having a counter cation selected from the group consisting of a hydrogen ion, an alkali metal ion, an alkaline-earth ion and a transition metal ion belonging to groups 8 to 10 in the periodic table; and the remaining R 1 to R 6 , which may be the same or different, represent hydrogen, alkyl having four or less carbon atoms or phenyl; or any two or more of R 1 to R 6 may be combined together to form an aromatic or aliphatic ring; and general formula 2: wherein at least one of R 7 to R 10 represents a sulfonic acid group having a counter cation selected from the group consisting of a hydrogen ion, an alkali metal ion, an alkaline-earth ion and a transition metal ion belonging to groups 8 to 10 in the periodic table; and the remaining R 7 to R 12 , which may be the same or different, represent hydrogen, alkyl having four or less carbon atoms or phenyl; or any two or more of R 7 to R 10 may be combined together to form an aromatic or aliphatic ring.

Claims

exact text as granted — not AI-modified
1 . A dopant comprising at least one of aromatic sulfonic acid derivatives represented by general formula 1:  
       
         
           
           
               
               
           
         
         wherein at least one of R 1  to R 6  represents a sulfonic acid group having a counter cation selected from the group consisting of a hydrogen ion, an alkali metal ion, an alkaline-earth ion and a transition metal ion belonging to groups 8 to 10 in the periodic table; and the remaining R 1  to R 6 , which may be the same or different, represent hydrogen, alkyl having four or less carbon atoms or phenyl; or any two or more of R 1  to R 6  may be combined together to form an aromatic or aliphatic ring; and general formula 2:  
         
           
             
             
                 
                 
             
           
         
         wherein at least one of R 7  to R 10  represents a sulfonic acid group having a counter cation selected from the group consisting of a hydrogen ion, an alkali metal ion, an alkaline-earth ion and a transition metal ion belonging to groups 8 to 10 in the periodic table; and the remaining R 7  to R 12 , which may be the same or different, represent hydrogen, alkyl having four or less carbon atoms or phenyl; or any two or more of R 7  to R 10  may be combined together to form an aromatic or aliphatic ring.  
       
     
     
         2 . The dopant as claimed in  claim 1  wherein the counter cation to the sulfonic acid group in general formula 1 or 2 is selected from the group consisting of hydrogen, sodium, potassium and iron(III) ions.  
     
     
         3 . The dopant as claimed in  claim 2  wherein in the sulfonic acid derivative represented by general formula 1 or 2, all of R 1  to R 12  other than the sulfonic acid group having the counter cation represent hydrogen.  
     
     
         4 . The dopant as claimed in  claim 3  wherein the aromatic sulfonic acid derivative comprises an aromatic sulfonic acid derivative represented by general formula 1.  
     
     
         5 . The dopant as claimed in  claim 3  wherein the aromatic sulfonic acid derivative comprises an aromatic sulfonic acid derivative represented by general formula 2.  
     
     
         6 - 9 . (Canceled)  
     
     
         10 . The dopant as claimed in  claim 1  wherein in the sulfonic acid derivative represented by general formula 1 or 2, all of R 1  to R 12  other than the sulfonic acid group having the counter cation represent hydrogen.  
     
     
         11 . The dopant as claimed in  claim 10  wherein the aromatic sulfonic acid derivative comprises an aromatic sulfonic acid derivative represented by general formula 1.  
     
     
         12 . The dopant as claimed in  claim 2  wherein the aromatic sulfonic acid derivative comprises an aromatic sulfonic acid derivative represented by general formula 1.  
     
     
         13 . The dopant as claimed in  claim 1  wherein the aromatic sulfonic acid derivative comprises an aromatic sulfonic acid derivative represented by general formula 1.  
     
     
         14 . The dopant as claimed in  claim 10  wherein the aromatic sulfonic acid derivative comprises an aromatic sulfonic acid derivative represented by general formula 2.  
     
     
         15 . The dopant as claimed in  claim 2  wherein the aromatic sulfonic acid derivative comprises an aromatic sulfonic acid derivative represented by general formula 2.  
     
     
         16 . The dopant as claimed in  claim 1  wherein the aromatic sulfonic acid derivative comprises an aromatic sulfonic acid derivative represented by general formula 2.
