Microporous supramolecular coordination compounds as chemosensory photonic lattices.

Chemical sensing–whether for human health assessment, environmental quality monitoring, or myriad other purposes–generally entails: a) recognition and binding, adsorption, or other interaction with the molecule or ion to be sensed, and b) transduction of the recognition/binding event into an externally observable signal.[1] Coordination-based supramolecular chemistry, with its ability to generate an enormous Scheme 4. Boronic ester annulation/Diels±Alder cycloaddition sequence performed on the high capacity bead-linker reagent used in a one-bead, one-stock solution platform for chemical genetics. a) 1-propynylmagnesium bromide, THF, 0 C RT; b) 4 (10 equiv), 5 (15 mol%), CH2Cl2, 40 C; c) N-benzylmeleimide (8 equiv), PhMe, 80 C; d) H2O2, NaOH, THF; e) HF ¥ pyr/pyr, THF. pyr pyridine.
