Abstract
Methods for producing regioregular poly(aryl ethynyl)-poly(aryl vinyl) and monomers for preparing the regioregular poly(aryl ethynyl)-poly(aryl vinyl) polymers are described herein. Regioregular poly(aryl ethynyl)-poly(aryl vinyl) are useful for electronics, among other things.
Claims41
A method for making a polymer, the method comprising:
- combining a silylalkynyl dialkoxyl arylaldehyde and a X-substituted dialkoxyl arylphosphonate;
- and
- contacting the silylalkynyl dialkoxyl arylaldehyde and the X-substituted dialkoxyl arylphosphonate under conditions that provide for coupling of the silylalkynyl dialkoxyl arylaldehyde and the X-substituted dialkoxyl arylphosphonate to provide a X-substituted silylalkynyl diarylethene.

A method for producing a monomer, the method comprising:
- providing a monoalkoxyl para-substituted arene;
- placing the monoalkoxyl para-substituted arene under conditions that allow a protecting group to be introduced at a non-alkylenated substituent of the monoalkoxyl para-substituted arene to provide a protected monoalkoxyl para-substituted arene;
- and
- placing the protected monoalkoxyl para-substituted arene under conditions that allow the protected monoalkoxyl para-substituted arene to be halogenated to provide a protected X-substituted monoalkoxyl arene.
