Upconversion Lanthanide-Based 2D Metal-Organic Frameworks for Multimode Information Encryption

Author(s): Chen J; Xie Y; Yang W; Sun R; Xing F; Mandl GA; Capobianco JA; Sun L;

Luminescent 2D metal-organic frameworks (MOFs) are a class of metal-organic framework materials expanded in a 2D plane, which have a wide range of applications in fields of optoelectronic devices, sensors, and information storage due to their unique layered structure and excellent optical properties. Currently, research on luminescent 2D MOFs mainly focus ...

Synthesis, Characterization and Photophysical Properties of a New Family of Rare-earth Cluster-based Metal-organic Frameworks

Author(s): Bicalho HA; Copeman C; Barbosa HP; Donnarumma PR; Davis Z; Quezada-Novoa V; Velazquez-Garcia JJ; Liu N; Hemmer E; Howarth AJ;

In this work, nine new rare-earth metal-organic frameworks (RE-MOFs, where RE = Lu(III), Yb(III), Tm(III), Er(III), Ho(III), Dy(III), Tb(III), Gd(III), and Eu(III)) isostructural to Zr-MOF-808 are synthesized, characterized, and studied regarding their photophysical properties. Materials with hig ...

Mechanochemical Synthesis of Boroxine-linked Covalent Organic Frameworks

Author(s): Hamzehpoor E; Effaty F; Borchers TH; Stein RS; Wahrhaftig-Lewis A; Ottenwaelder X; Frišcic T; Perepichka DF;

We report a rapid, room-temperature mechanochemical synthesis of 2- and 3-dimensional boroxine covalent organic frameworks (COFs), enabled by using trimethylboroxine as a dehydrating additive to overcome the hydrolytic sensitivity of boroxine-based COFs. The resulting COFs display high porosity a ...

The Effect of Linker-to-Metal Energy Transfer on the Photooxidation Performance of an Isostructural Series of Pyrene-Based Rare-Earth Metal-Organic Frameworks

Author(s): Quezada-Novoa V; Titi HM; Villanueva FY; Wilson MWB; Howarth AJ;

The tetratopic linker, 1,3,6,8-tetrakis(p-benzoic acid)pyrene (H4 TBAPy) along with rare-earth (RE) ions is used for the synthesis of 9 isostructures of a metal-organic framework (MOF) with shp topology, named RE-CU-10 (RE = Y(III), Gd(III), Tb(III), Dy(III), Ho(III), Er(III), Tm(III), Yb(III), and Lu(III)). The synthesis of each RE-CU-10 analogue require ...

Upconversion Luminescence through Cooperative and Energy-Transfer Mechanisms in Yb3+ -Metal-Organic Frameworks

Author(s): Xie Y; Sun G; Mandl GA; Maurizio SL; Chen J; Capobianco JA; Sun L;

Lanthanide-doped metal-organic frameworks (Ln-MOFs) have versatile luminescence properties, however it is challenging to achieve lanthanide-based upconversion luminescence in these materials. Here, 1,3,5-benzenetricarboxylic acid (BTC) and trivalent Yb3+ ions were used to generate crystalline Yb-BTC MOF 1D-microrods with upconversion luminescence under ne ...

A historical perspective on porphyrin-based metal-organic frameworks and their applications

Author(s): Zhang X; Wasson MC; Shayan M; Berdichevsky EK; Ricardo-Noordberg J; Singh Z; Papazyan EK; Castro AJ; Marino P; Ajoyan Z; Chen Z; Islamoglu T; Howarth AJ; Liu Y; Majewski MB; Katz MJ; Mondloch JE; Farha OK;

Porphyrins are important molecules widely found in nature in the form of enzyme active sites and visible light absorption units. Recent interest in using these functional molecules as building blocks for the construction of metal-organic frameworks (MOFs) have rapidly increased due to the ease in ...
