Conformationally Locked Tolans, β-Sheet Structures, and Photophysical Properties.


Conformationally locked tetrasubstituted tolans were synthesized by introducing a tether on the tolan. To demonstrate the utilities of these motifs, a β-hairpin structure (15) was synthesized, and its additional stabilizing effects were evaluated. Moreover, the photophysical properties of cyclic tolans and their β-sheet structure were investigated. The… (More)
