A white-light-emitting single MOF sensor-based array for berberine homologue discrimination

Abstract

With distinct responses of three fluorescent bands, a single white-light-emitting MOF was constructed and applied in array sensing for berberine homologue discrimination.

Porous organic–inorganic hybrid materials for catalysis, energy and environmental applications

“…For example, the specific binding of Zr(IV) with the phosphate groups of aptamers gives Zr-based materials (UiO-66 and UiO-66-NH 2 ) an upper hand over others. 203 With respect to dimensionality, 2D materials have an edge over their 3D counterparts given that they possess high permeability and more exposed active sites. Achieving a uniform size distribution with structural consistency of the hybrid porous materials and controllable doping of aptamers in the porous matrix are few of the major challenges in this domain.…”

Design and properties of multiple-emitter luminescent metal–organic frameworks

“…Thus, the integration of more than one chromophore linker with a suitable metal center (that cannot quench the ligand-based emission) into a single MOF phase can fabricate multi-emitter LMOFs. 14,38 For example, the two chromophore linkers 1,3,5-tris(4-carboxyphenyl)-benzene (btb 3À ) and 5-amino-1-H-tetrazolate (atz À ) were used to prepare the LMOF [(CH 3 ) 2 NH 2 ][Zn(btb) 2/3 (atz)] with an anionic framework. 60 Two atz À linkers coordinate to a single tetrahedral Zn 2+ center which brings not only the two atz À chromophores but also the atz À and btb 3À chromophores into close proximity to enable electronic interactions between these linker chromophores (Fig.…”

“…6,12 Furthermore, the relative intensity changes for the different emissions in multi-emitter LMOFs can act as a luminescent signal for specific analytes. [13][14][15] This provides multidimensional recognition, reproducibility, self-calibration and visible sensing. To date, multi-emitter materials have been developed in several chemical systems such as small chromophore molecules, 16 polymers, 17 and nanoparticles.…”

Recent Progress on Luminescent Metal-Organic Framework-Involved Hybrid Materials for Rapid Determination of Contaminants in Environment and Food

“…MOFs have been used or designed to satisfy the demands of various applications over the last decades. The varied structures and exceptional properties also make MOFs enchanting for possible applications, ranging from gas storage [55] to liquid/ solid-phase separation [56,57], sensing [58], drug delivery [59], heterogeneous catalysis [60] and proton conductivity [61].…”
