Helquat-Induced Chiroselective Aggregation of Au NPs
Original language description
Au nanoparticles (NPs) are functionalized with chiral (R)- or (S)-binaphthol phenylboronic acid ligands, (1a) or (1b). The (R)- or (S)-binaphthol phenylboronic acid ligands form donor-acceptor complexes with the chiral dicationic helicene, helquat (P)-HQ2+ or (M)-HQ2+, (2a) or (2b). The association constants between (1a)/(2a) and (1a)/(2b) correspond to (7.0 +/- 0.5) x 105 M-1 and (2.5 +/- 0.3) x 105 M-1, respectively, whereas the association constants between (1b)/(2b) and (1b)/(2a) correspond to (4.0+/- 0.5)x 105 M-1 and (1.8 +/- 0.3)x 105 M-1, respectively. Chiroselective aggregation of chiral binaphthol phenylboronic acid-capped Au NPs triggered by the chiral helquats, is demonstrated.
