Lanthanide-based luminescent hybrid materials.

Exposure to even very low levels of lead, cadmium, and mercury ions is known to cause neurological, reproductive, cardiovascular, and developmental disorders, which are more serious problems for children particularly. Accordingly, great efforts have been devoted to the development of fluorescent and colorimetric sensors, which can selectively detect lead, cadmium, and mercury ions. In this critical review, the fluorescent and colorimetric sensors are classified according to their receptors into several categories, including small molecule based sensors, calixarene based chemosensors, BODIPY based chemosensors, polymer based chemosensors, DNA functionalized sensing systems, protein based sensing systems and nanoparticle based sensing systems (197 references).

Fluorescent and colorimetric sensors for detection of lead, cadmium, and mercury ions

Challenges and breakthroughs in recent research on self-assembly

There is great need for stand-alone luminescence-based chemosensors that exemplify selectivity, sensitivity, and applicability and that overcome the challenges that arise from complex, real-world media. Discussed herein are recent developments toward these goals in the field of supramolecular luminescent chemosensors, including macrocycles, polymers, and nanomaterials. Specific focus is placed on the development of new macrocycle hosts since 2010, coupled with considerations of the underlying principles of supramolecular chemistry as well as analytes of interest and common luminophores. State-of-the-art developments in the fields of polymer and nanomaterial sensors are also examined, and some remaining unsolved challenges in the area of chemosensors are discussed.

Supramolecular Luminescent Sensors

Cyclodextrins (CDs) are a class of cyclic oligosaccharides with six to eight D-glucose units linked by α-1,4-glucose bonds, and their capability of forming stable complexes with various organic/inorganic/biological molecules and ions makes them attractive as building blocks for the construction of nano-scale supramolecular systems. This tutorial review deals with representative contributions in the construction and the structural characteristics of CD-based supramolecular assemblies as well as their interactions with biologically important substrates. This review is addressed to students and researchers interested in supramolecular chemistry, biochemistry and nanotechnology.
