Directional self-assembly of gold nanorods into 1D and 2D arrays by quadruple hydrogen bonding†
Abstract
A facile, bottom-up technique is developed to produce highly ordered end-to-end and side-by-side assembly of gold nanorods (GNRs) via quadruple hydrogen bonding. The switching between end-to-end and side-by-side aggregation modes can be achieved by tuning the crosslinker concentration.
