title: Determination of orientational isomerism in rhodium(II) metallopeptides by pyrene fluorescence.
abstract: Rhodium(II) metallopeptides display useful secondary structure, self-assembly, and catalytic activity. The bis-peptide complexes exhibit subtle orientational isomerism that affects function, but is challenging to characterize. We report that pyrene excimer fluorescence measurements provide a conclusive proof of isomeric structure.
