WebWe demonstrate circular dichroism (CD) in the second harmonic generation (SHG) signal from chiral assemblies of G-shaped nanostructures made of gold. The arrangement of the G shapes is crucial since upon reordering them the SHG-CD effect disappears. Microscopy reveals SHG “hotspots” assemblies, which originate in enantiomerically sensitive … WebIt has been demonstrated that by incorporating nonlinear interaction with circularly‐polarized excitation, second‐harmonic generation circular dichroism (SHG‐CD) can provide much higher signal contrast. However, previous CD and SHG‐CD studies are mostly limited to probe chiralities at surfaces and interfaces.
