Lumophore-spacer-receptor systems are not by any means limited to the ami-noalkyl aromatic family even if we focus on the receptor unit. Still, the latter family is likely to remain a major provider of ionically switchable luminescent devices. Aminoalkyl aromatics also serve as the platform for the development of luminescent PET sensors for a whole class of nonionic saccharides. While aliphatic amines, either singly or in arrays, can serve as receptors for a variety of cationic... 

Table 4.1 presents potential platform chemicals and their possible derivatives that could be produced from bioconversion of saccharides. Some of these platform chemicals are already industrially produced via fermentation, such as bioethanol, citric acid, glutamic acid, lactic acid and 1,3-propanediol...

Combinations of the very simple spin-coated reactive polymer films discussed in Sect. 2.1.4 with the micro- and nanopatterning approaches studied and refined in model studies on weU-defined macromolecular (dendrimer) systems are ciu rently being investigated with substantial success. Thus, the lessons learned in these model studies can be applied to practical formats in order to provide reactive micro- and nanopatterned platforms for the development of biosensors, biochips (DNA, proteins, saccharides, and so on) and studies of cell-cell and ceU-substrate interactions. 

If the answer is YES, the route to crown and aza-crown ethers (and their analogs) with sucrose scaffold is open. Sugars are convenient and easily accessible starting platforms for the preparation of chiral macrocyclic receptors. This is true for monosaccharides (as mentioned already in the INTRODUCTION) however, much less is known about chiral macrocycles with di-saccharide scaffold.
