Construction of 2D extended cocrystals on the Au(111) surface via I⋯Oaldehyde halogen bonds†
Abstract
2D extended organic cocrystals were constructed using 1,4-diiodotetrafluorobenzene and aromatic aldehydes via I⋯Oaldehyde halogen bonds on an Au(111) surface. The competition and synergy of halogen bonds and hydrogen bonds in 2D co-crystallization were revealed by scanning tunneling microscopy.
