abstract = {A novel synthetic strategy based on a bifunctional stapled chiral nucleus from which segments of different
lengths can be added to both ends of o-phenylene ethynylenes (o-OPEs) has been developed to obtain a
new type of foldamer and a novel chiral Pd2L2 metallacycle. For the first time, an enantiopure fully conjugated
helical foldamer having 14 phenyl rings and 13 alkynes is reported. The folded structure has four
complete loops and is able to host three Ag(I) cations in their cavity with high binding constants. The
complete photophysical and chiroptical (ECD, CPL and VCD) characterization of these foldamers has
shown that these molecules show intense chiroptical responses with dissymmetry ratios in the range of
10−2. Theoretical modeling of these systems reveals the origin of these remarkable responses and points
out a potential connection with the chiral induced spin selectivity (CISS) effect. The magnetic dipole
moment is proposed as a key physical variable connecting the chiroptical properties and CISS-based spin
filtering properties observed in chiral compounds.},
