Leaving a lasting impression: Molecularly imprintedpolymers (MIPs) featuring neutral binding sites for phosphotyrosine (P) is also shown to have affinity for sulfotyrosine (S) and a sulfotyrosine‐containing peptide. The MIPs were capable of selectively capturing both a phosphorylated and a sulfated peptide in a mixture and could release the peptides separately based on elution conditions.

The organophosphonate-substituted alkoxides [(Bu4N)-N-n](2)[Ti(OMe)(3)(O3PPh)}(2)] (1) and [(Bu4N)-N-n](2)[Nb(OMe)(3)(O3PPh)}(2)(mu-O)] (2) have been prepared from [(Bu4N)-N-n][PhPO3H] and the metal alkoxides Ti(OMe)(4) or Nb(OMe)(5) respectively. In 1, the bridging phenylphosphonates occupy trans coordination sites, whereas in 2, a cis-bridging geometry is adopted. (C) 1998 Elsevier Science S.A.
