Resumo(s)
Anions are ubiquitous and very important species in biological, medicinal,
industrial and environmental processes. In biology, anions are essential for
normal metabolic functions, where their specific recognition, transport and
detection play a very important role. On the other hand, the uncontrolled release
of anions into the environment poses a significant threat.
The development of synthetic receptors capable of sequestering anions
should, therefore, provide solutions to a number of problems of current interest.
To be suitable for real-life applications, as for instance the detection and
quantification of biologically active anions in clinical laboratories or the
environmental monitoring and/or removal of pollutants, synthetic receptors need
to be able to function in aqueous solution. However, due to the high dielectric
constant and good hydrogen bond donor and acceptor capabilities, water is the
most challenging medium for anion recognition.(...)
