To utilize molecularly imprinted polymers (MIPs) as responsive recognition phases in sensors, the employment of fluorescent molecules or nanoparticles (NPs) that show prominent changes in their spectroscopic properties after binding of the target molecule in the MIP’s cavity is particularly attractive. Such fluorescent MIPs (fMIPs) act through target-induced quenching, enhancement, or spectral shifts of the fluorescence. This contribution introduces different strategies of incorporation of fluorescent dyes, probes, and NPs into fMIPs. In addition, various sensing mechanisms are reviewed, and depending on the application of the sensor, the different deployable formats, their advantages, drawbacks, and impact will be presented and discussed.

T1 - Quantum Dot Material Systems, Compositional Families N2 - Following the discovery of the quantum confinement effect in the early 1980s, it took more than 10 years to be able to synthesize monodisperse colloidal quantum dots (QDs) using organometallic chemistry approaches. The researchers behind these pioneering works, Alexey Ekimov, Louis Brus, and Moungi Bawendi, were awarded the Nobel Prize in Chemistry in 2023, exactly 30 years after the seminal report on the preparation of cadmium chalcogenide QDs. From the synthetic point of view, this approach, relying on the fast injection of a chalcogenide precursor dissolved in a tertiary phosphine into a hot solution of the cadmium precursor in a coordinating solvent (trioctylphosphine oxide, TOPO) acting at the same time as surface ligand, was revolutionary. It enabled the fast synthesis of wellcrystallized CdS, CdSe, and CdTe QDs of low size dispersion and high colloidal stability, whose size and hence optical and electronic properties could be conveniently tuned with the reaction time. Due to the comparable ease of this method and the later developed shelling procedures with ZnS, ZnSe, CdS, and mixtures or alloys of these materials, CdSe has become the workhorse for the entire QD field, covering the whole visible range of absorption and emission. Meanwhile, several breakthroughs have been achieved, which enabled us to bring QDs to their maturity of today and integrate them in several applications, in particular those relying on their exceptional luminescence properties, such as biological imaging as well as displays and screens. For such real-life applications, the quest for less toxic, safer-to-use, and environmentally friendly materials is of utmost importanceand a highly active research field. The use of cadmium- and lead-based materials is severely restricted by regulations such as the RoHS directive of the European Union: the maximum concentrations of lead and cadmium are 0.1 and 0.01% by weight, respectively, in all homogeneous materials in electrical and electronicequipment. Several families of alternative materials have been explored, with the most important ones for display technologies being indium phosphide (InP)- and ternary chalcopyrite-type QDs.
