Abstract: By incorporating the amide groups into building blocks, two M4L4 molecular tetrahedrons were designed and synthesized for selective recognition of natural saccharides. Tetrahedron Ce-TBSB showed fluorescent enhancement in the presence of natural monosaccharides, whereas the larger analogy Ce-TBAB having twelve additional free amide groups exhibited fantastically selective luminescent enhancement toward sucrose over other natural mono- and di-saccharides. The selective responses of the tetrahedrons thus should be attributed to both the size-fitting of the cavities and the potential hydrogen bond interaction of the amide groups. (C) 2014 Elsevier B.V.
