The molecular recognition capability of these particles enables their use in research, diagnostic, therapeutic, and separation applications. The nanoparticles of the invention may be formed by contacting target template molecules with a set of building blocks (which includes the high affinity molecule as one subset of the building block set), which are then polymerized into a network.

Abstract: A series of ortho isomers of meso tetrakis N-alkylpyridylporphyrins (alkyl being methyl, ethyl, n-propyl, n-butyl, n-hexyl, and n-octyl) and their Mn(III) complexes were synthesized and characterized by elemental analysis, uv/vis spectroscopy, electrospray ionization mass spectrometry and electrochemistry. An increase in the number of carbon atoms in the alkyl chains from 1 to 8 is accompanied by an increase in: (a) lipophilicity measured by the chromatographic retention factor, Rf; (b) metal-entered redox potential, E1/2 from +220 to +367 mV vs NHE, and (c) proton dissociation constant, pKa2 from 10.9 to 13.2. A linear correlation was found between E1/2 and Rf of the Mn(III) porphyrins and between the pKa2 and Rf of the metal-free compounds. As the porphyrins become increasingly more lipophilic, the decrease in hydration disfavors the separation of charges, while enhancing the electron-withdrawing effect of the positively charged pyridyl nitrogen atoms.
