First peptide-based system of rigid donor-rigid interchromophore spacer-rigid acceptor: A structural and Photophysical study

Therationaldesign, preparationandstructureassignment of a rigid donor–spacer–acceptor system is simply achieved by the use of a strategy based on the synthesis of a peptide from conformationally restricted Cα-tetrasubstituted α-amino acids (see figure), and X-ray diffraction and photophysical methods for crystal state and solution structure determination.
