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

The new Schiff bases bearing anthracene unit were synthesized from 2-aminoanthracene and various aldehydes such as: benzaldehyde, 4-(diphenylamino)benzaldehyde, 9-phenanthrenecarboxaldehyde, 9-anthracenecarboxaldehyde, and biphenyl-4-carboxaldehyde, 2-naphthaldehyde. Resulted azomethines were characterized by IR, NMR (
