TL;DR: Fluorophores can be connected to ion receptors so as to permit extensive overlap, be geometrically orthogonal or be separated by a spacer as mentioned in this paper, which has led to applications as ion sensors or switches.
Abstract: Fluorophores can be connected to ion receptors so as to permit extensive overlap, be geometrically orthogonal or be separated by a spacer. Each of these three formats 1-3 has led to applications as ion sensors or switches. We focus on 'fluorophore-spacer-receptor' systems whose modular structure allows semiquan- titative design according to the principle of photoinduced electron transfer (PET). The fluorescence of these systems can be switched 'on' or 'off' when confronted with ions. Several new examples 15-17 responding to Na', H~N'CH~CHZCH~CO~ and H' are described. 17 and 18 are cases where kinetic factors become important in addition to the usual thermodynamic design criteria. Expansion of the basic three- module system by the addition of a separate receptor with a different ion binding profile as in 19 gives rise to molecular AND logic gates. On the other hand, OR logic gates such as 20 can be obtained from the basic system provided that the receptor is deliberately chosen to be nonselective under the conditions of use.

TL;DR: In this paper, a brief discussion of luminescent sensing and luminescence PET (photo-induced electron transfer) sensing in particular, some new developments in the field are highlighted, including auxiliary lumophores for internal referencing and lanthanide lumophore.
Abstract: Following a brief discussion of luminescent sensing and luminescent PET (photoinduced electron transfer) sensing in particular, some new developments in the field are highlighted. Lumophores with ICT (internal charge transfer) excited states, auxiliary lumophores for internal referencing and lanthanide lumophores are examined in this context.

TL;DR: Anion recognition chemistry has grown from its beginnings with positively charged ammonium cryptand receptors for halide binding to a plethora of charged and neutral, cyclic and acyclic, inorganic and organic supramolecular host systems for the selective complexation, detection, and separation of anionic guest species.
Abstract: Anion recognition chemistry has grown from its beginnings in the late 1960s with positively charged ammonium cryptand receptors for halide binding to, at the end of the millennium, a plethora of charged and neutral, cyclic and acyclic, inorganic and organic supramolecular host systems for the selective complexation, detection, and separation of anionic guest species. Solvation effects and pH values have been shown to play crucial roles in the overall anion recognition process. More recent developments include exciting advances in anion-templated syntheses and directed self-assembly, ion-pair recognition, and the function of anions in supramolecular catalysis.
