The techniques of molecular imprinting and sensitized lanthanide
luminescence have been combined to create the basis for a sensor
that can selectively measure a specific organophosphorous
compound. A complex of polymerizable sensitizing ligand
europium (III) and an organophosphorous compound are
copolymerized in a cross-linked polymer matrix. The best
coordinators are trifluoromethyl substituted
The best polymerization mechanism is by Reversible Addition
Fragmentation Transfer polymerization. This approach is
allowing the production of soluble processable imprinted
materials. Analogous methodologies are currently being applied
to the production of sensors for the detection and determination
of drugs of abuse, explosives and meat spoilage. Drugs are
measured in an analogous manner to the nerve agents while the
explosives are being detected by the production of
charge-transfer complexes between the explosives molecules,
(acceptor) and immobilized amines (donor). Meat spoilage
sensing is obtained using luminescence from a transition metal
macrocyclic complex. The materials are also capable of
providing highly selective binding sites to other transducers
such as quartz crystal microbalance and surface plasmon
An additional thrust is to develop new solid phase extractants
for the removal of metal ions from environmental and wastewater
and to serve as the basis for selective ion sensors. Rather
than continuing to test existing extractants by an Edisonian
approach in the hope that an excellent extractant may be found,
we rely on chemical insights into what makes a good extractant.
The sources of these insights include coordination number,
coordination geometry, ionic size, ionic shape, and
thermodynamic affinity. Selectivity is obtained by providing
the polymeric extractants with cavities lined with complexing
ligands so arranged as to match the charge, coordination number,
coordination geometry, and size of the metal ion. Using the
metal ion as a template around which polymerizable monomeric
complexing ligands are polymerized produces these
cavity-containing polymers. The complexing ligands are ones
containing functional groups known to form highly stable
complexes with a specific metal ion and less stable complexes
with other cations. We have developed sequestering agents for
lead and uranium as well as electrochemical and optical sensors
based on this approach. We are now applying this experience in
selectivity toward preparing other form factors such as
imprinted ion exchange resin beads.
