Bioinspired energy-transfer arrays composed of electronically coupled BODIPY dyads as energy donors and chlorins as energy acceptors feature ultrafast (~10 ps) energytransfer, which is consistent with the Förster mechanism. The energy-transfer rate in the arrays is nearly independent of the position at which energy donor is attached to the chlorin or of the nature of the intervening linker.

Three free base porphyrins have been prepared that bear a polar and facially encumbering 2,4,6-tris(carboxymethoxy)phenyl Motif at One meso (5-) position. The only other substituent (15-position) comprises phenyl, formyl, or p-aminophenyl. The porphyrins exhibit solubility in water (or aqueous buffer Solutions) at pH >= 7 and concentrations >1 mM at room temperature. The concise syntheses, water solubility, and bioconjugatable handle make these porphyrin constructs Suitable for biological applications. (C) 2008 Elsevier Ltd. All rights reserved.
