Molecule-based magnetic polymers with high Curie temperature and methods of preparing are provided. In particular, magnetic polymers having repeating units of an electron-donor metallocene-containing monomer covalently bonded to an electron-acceptor monomer having a plurality of unpaired electrons are disclosed. Intrinsically homogeneous magnetic fluids (liquid magnets) and methods of preparing are also provided.

The present invention generally relates to methods for modulating the optical properties of a luminescent polymer via interaction with a species (e.g., an analyte). In some cases, the present invention provides methods for determination of an analyte by monitoring a change in an optical signal of a luminescent polymer upon exposure to an analyte. Methods of the present invention may be useful for the vapor phase detection of analytes such as explosives and toxins. The present invention also provides methods for increasing the luminescence intensity of a polymer, such as a polymer that has been photobleached, by exposing the luminescent polymer to a species such as a reducing agent.
