Pyrene-based metal organic frameworks: from synthesis to applications

Abstract

Pyrene-based MOFs have several applications; including luminescence, photocatalysis, adsorption and separation, heterogeneous catalysis, electrochemical applications and bio-medical applications.

Modulating Photo- and Radioluminescence in Tb(III) Cluster-Based Metal–Organic Frameworks

“…The observed photo-and radioluminescence emission of Tb-CU-10, centered at 525 nm, is strongly red-shifted compared to the free linker (420 nm), 44 a commonly observed feature of excimer emission in pyrene-based MOFs. [45][46][47] Previous studies demonstrate that excimer formation in MOFs is favorable when the center-center distance between pyrene units is in the range of 8.8 -11 Å, and the measured distance in Tb-CU-10 is 11 Å, in agreement with previous findings. 46 Furthermore, the pyrene-pyrene and pyrene-phenyl torsional angles are known to play a role in excimer formation, 46 where Tb-CU-10 exhibits torsional angles of 60 and 59° for pyrene-pyrene and pyrene-phenyl, respectively.…”

Biomimetic smart nanoplatform for dual imaging-guided synergistic cancer therapy

“…23,24 Moreover, by selecting suitable organic ligands such as pyrene, porphyrin, or imidazole, diverse MOFs with desirable physicochemical properties can be obtained. [25][26][27] For instance, MOFs of Cu-porphyrin derivatives have been designed for PDT with depletion of GSH and H 2 O 2 levels in the TME. 28 The integration of Mn into porphyrin MOFs has been proven to be a promising agent for PTT and MRI.…”

Highly Fluorescent Dyes Containing Conformationally Restrained Pyrazolylpyrene (Pyrazoolympicene) Chromophore

“…Moreover, it can also be easily functionalized [7][8][9]. Due to these properties, pyrene has been the subject of interest in numerous studies aimed at its modification to obtain useful fluorophores for practical applications in various branches of science, ranging from optoelectronics to biology and medicine [4,7,[10][11][12][13][14]. Pyrazoles are another class of small molecule fluorophores exhibiting intense and tunable emission, thoroughly studied in recent years [15][16][17][18][19][20].…”
