Abstract

The supramolecular self-assembly of s-indacene-1,3,5,7(2H,6H)-tetrone (INDO₄) on Ag(111), Ag(100) and Ag(110) surfaces was studied using scanning tunneling microscopy (STM). Four similar brickwall-type phases were found and in two of them the molecules appeared with distinct alternating contrast. The origin of this effect is discussed in terms of molecular adaptation.
