Claims38
A compound having a structure of:
- wherein R1-R12 are each individually H, amino, alkynyl, substituted alkynyl, halogen, alkyl, aryl, substituted alkyl, substituted aryl, nitro, alkoxy, substituted alkoxy, cyano, thiol, substituted thiol, thioether, hydroxyl, heteroaryl, substituted heteroaryl, cycloalkyl, or substituted cycloalkyl, provided that at least two of R1-R12 are alkynyl or substituted alkynyl.
An indenofluorene that includes at least two alkynyl-containing substituents.
A method for making an alkynyl-substituted indeno[1,2-b]fluorene, comprising:
- reacting a dione-substituted indenofluorene with an alkyne to produce a hydroxy-functional intermediate;
- and
- reducing the hydroxy-functional intermediate to produce an alkynyl-substituted indeno[1,2-b]fluorene.
