TLDR
In this article, a deweloped procedure for the preparation of macrabicyclic ligands 1-11 containing pyridine, bipyridine and biisoquinoline groups was proposed.Abstract:
Sythetic procedures have been deweloped for the preparation of sodium and lithium cryptates of the macrabicyclic ligands 1–11 containing pyridine, bipyridine, and biisoquinoline groups. They involve stepwise construction of the bicyclic system as will as direct macrobicyclisation procedures (Scheme 1) and give access to both symmetrical and dissymmetrical structures. Marked cation template effects have been found that facilitate the cyclisation processes. The ligands 1–11 were isolated as their cryptates with Na+ or Li+ cations.read more

Fluorescent sensing of pyrophosphate and bis-carboxylates with charge neutral PET chemosensors.
TL;DR: The fluorescent photoinduced electron transfer chemosensors 2 and 3 were designed for the recognition of anions possessing two binding sides such as dicarboxylates and pyrophosphate; the anion recognition in DMSO takes place through the two charge neutral thiourea receptor sites with concomitant PET quenching of the anthracene moiety.

Rare earth cryptates and homogeneous fluoroimmunoassays with human sera.
TL;DR: The conditions under which the signal of these cryptates can be amplified through the use of nonradiative energy transfer are established and applied to homogeneous immunoassays by using allophycocyanin as the acceptor.

DNH deoxyribonucleohelicates : self assembly of oligonucleosidic double-helical metal complexes
TL;DR: This work presents a class of artificial systems, the nucleohelicates, which are of interest from both points of view because they combine the double-helical structure of thedouble-stranded metal complexes, the helicates2,3, with the selective interaction features of nucleic-acid bases.

Design of organic complexing agents Strategies towards properties
TL;DR: In this paper, it was shown that information stored in various structural features allows the thermodynamic and kinetic features of the complexation process to be monitored, and further progress may be achieved by making use of the feedback from present results to adjust and improve the model and to analyze the information-property relationship.
