Luminescent Sensing

Metal–organic frameworks (MOFs), as a class of crystalline hybrid architectures, consist of metal ions and organic ligands and have displayed great potential in luminescent sensing applications due to their tunable structures and unique photophysical properties. Until now, many studies have been reported on the development of MOF-based luminescent sensors, which can be classified into two major categories: MOF chemosensors based on reversible host–guest interactions and MOF chemodosimeters based on the irreversible reactions between targets with a probe. In this review, we summarize the recently developed luminescent MOF-based chemodosimeters for various analytes, including H2S, HClO, biothiols, fluoride ions, redox-active biomolecules, Hg2+, and CN−. In addition, some remaining challenges and future perspectives in this area are also discussed.

Post Functionalization

We report a new class of redox-­‐active vertex-­‐differentiated dodecaborate clusters featuring pentafluoroaryl groups. These [B12(OR)11NO2] clusters share several unique photophysical properties with their [B12(OR)12] analogues, while exhibiting significantly higher (+0.5 V) redox potentials. This work describes the synthesis, characterization, and isolation of [B12(O-­‐CH2C6F5)11NO2] clusters in all 3 oxidation states (dianion, radical, and neutral). Reactivity to post-­‐functionalization with thiol species via SNAr on the pentafluoroaryl groups is also demonstated.

A series of new porphyrazines with oligo(ethylene oxide) thioalkoxy side chains has been synthesized. Study of the phase transitions reveals the absence of liquid crystallinity. Due to the ethylene oxide moieties, the solubility in a variety of solvents is dramatically increased. This allowed the first study of solvent effects on the photophysical properties (absorption and emission) in water and chloroform. The complexation of the porphyrazines with the redox couple LiI / I 2 has been studied. No effect on the aggregate formation has been observed in solution, while in a film incorporation of an increased amount of LiI / I 2 leads to a disturbance of the aggregates. At temperatures up to 100°C the porphyrazine - LiI / I 2 complexes are stable in the liquid phase, but from 115°C onwards, small crystallites of LiI are formed in the isotropic liquid.
