The styryl dye (E)-2-[3-[4-(diphenylamine) phenyl]-1-(p-tolyl)-allylidene]-malononitrile (DFTAM) was prepared by Knoevenagel condensation using homogeneous and surface bound amino catalysts. The catalysis by surface bound piperazine allowed the study of the condensation reaction at a single molecule (SM) level using total internal
