Abstract:
A conjugated electroluminescent polymer comprised of monomer units having the structure of formula (I) whereinAr1 and Ar2 are independently selected from the group consisting of monocyclic, bicyclic and polycyclic arylene, heteroarylene, substituted arylene and substituted heteroarylene groups; L is alkylene, alkenylene, substituted alkylene, substituted alkenylene, heteroalkylene, heteroalkenylene, substituted heteroalkylene, substituted heteroalkenylene, arylene, heteroarylene, substituted arylene, or substituted heteroarylene; m is zero or 1; n is zero or 1; Q1 is selected from the group consisting of aryl, heteroaryl, substituted aryl, substituted heteroaryl, alkyl, and substituted alkyl; Q2 is selected from the group consisting of H, aryl, heteroaryl, substituted aryl, substituted heteroaryl, alkyl, and substituted alkyl; and Q3 is selected from the group consisting of alkyl, substituted alkyl, heteroalkyl, and substituted heteroalkyl, with the proviso that when m is 1, Q2 is other than H; and Aâˆ’is a negatively charged counterion, and further wherein when n is zero, at least one of the following is satisfied; (a) m is 1; and (b) at least one of Ar1, Ar2, Q1, and Q2 is substituted with a substituent selected from â€”SO3H, â€”COOH, or â€”P(O)OH2 groups; C1-C20 hydrocarbyl or heteroatom-containing C1-C20 hydrocarbyl substituted with one or more â€”SO3H, â€”COOH, or â€”P(O)OH2 groups; or with organic or inorganic sulfonate, carboxylate or phosphonate salts; or a combination thereof.
