Claims24
An optoelectronic device comprising a charge transfer layer including a first semiconductive polymer comprising one or more zwitterions wherein the first semiconductive polymer consists of a first fluorene repeat unit having at least one zwitterionic substituent and a second fluorene repeat unit, wherein the zwitterionic substituent comprises at least one quaternary amine group and at least one sulfonate group.
A semiconductive polymer consisting of a first fluorene repeat unit having at least one zwitterionic substituent and a second fluorene repeat unit, wherein the zwitterionic substituent comprises a first cationic charge center separated from a first anionic charge center by more than 2 atomic centers, wherein the zwitterionic substituent comprises at least one quaternary amine group and at least one sulfonate group.
A method of manufacturing an electrically semiconductive zwitterionic polymer comprising:
- polymerizing at least a first conjugated monomer and a second conjugated monomer to form a conductive polymer;
- and,
- reacting the polymer with at least one zwitterion forming reactant to form an electrically semiconductive zwitterionic polymer,
- the electrically semiconductive zwitterionic polymer consisting of a first fluorene repeat unit having at least one zwitterionic substituent and a second fluorene repeat unit, wherein the zwitterionic substituent comprises at least one quaternary amine group and at least one sulfonate group.
