Abstract

Abstract Dynamic surfaces: The conformational transition of 2, 6-bis (1-aryl-1, 2, 3-triazol-4- yl) pyridine (BTP) derivatives, triggered by a change in pH, has been observed with a sub- nm resolution by STM at the solid–liquid interface. Upon addition of trifluoroacetic acid two different BTP molecules, each forming a highly ordered physisorbed monolayer, underwent significant conformational changes from their “rosette” to their “tetragon” forms, as ...
