Phenyl Ring Dynamics in a Tetraphenylethylene-Bridged Metal–Organic Framework: Implications for the Mechanism of Aggregation-Induced Emission
Natalia B. Shustova,Ta-Chung Ong,Anthony F. Cozzolino,Vladimir K. Michaelis,Robert G. Griffin,Mircea Dincă +5 more
TL;DR: It is shown that a perdeuterated TPE-based metal-organic framework (MOF) serves as an excellent platform for studying the low-energy vibrational modes of AIE-type chromophores, and a set of design criteria for the development of tunable turn-on porous sensors constructed from AIe-type molecules is proposed.
Phenyl Ring Dynamics in a Tetraphenylethylene-Bridged Metal–Organic Framework: Implications for the Mechanism of Aggregation-Induced Emission
Natalia B. Shustova,Ta-Chung Ong,Anthony F. Cozzolino,Vladimir K. Michaelis,Robert G. Griffin,Mircea Dincă +5 more
TL;DR: In this paper, a perdeuterated tetraphenylethylene (TPE) based metal-organic framework was used to study the low-energy vibrational modes of aggregation-induced emission (AIE) type chromophores.
Journal ArticleDOI
Thiophene-based covalent organic frameworks.
TL;DR: The synthesis and characterization of covalent organic frameworks incorporating thiophene-based building blocks are reported, showing that these are amenable to reticular synthesis, and that bent ditopic monomers, such as 2,5-thiophenediboronic acid, are defect-prone building blocks that are susceptible to synthetic variations during COF synthesis.
Journal ArticleDOI
Dynamic DMF Binding in MOF-5 Enables the Formation of Metastable Cobalt-Substituted MOF-5 Analogues.
Carl K. Brozek,Vladimir K. Michaelis,Ta-Chung Ong,Luca Bellarosa,Núria López,Robert G. Griffin,Mircea Dincă +6 more
TL;DR: Understanding the dynamic behavior of MOF-5 leads to a rational low-tem temperature cation exchange approach for the synthesis of metastable Zn4–xCoxO(terephthalate)3 (x > 1) materials, which have not been accessible through typical high-temperature solvothermal routes thus far.
Journal ArticleDOI
Sensitivity-enhanced NMR reveals alterations in protein structure by cellular milieus.
Kendra K. Frederick,Vladimir K. Michaelis,Björn Corzilius,Ta-Chung Ong,Angela C. Jacavone,Robert G. Griffin,Susan Lindquist +6 more
TL;DR: In this article, the same authors applied DNP NMR to investigate the structure of a protein containing both an environmentally sensitive folding pathway and an intrinsically disordered region, the yeast prion protein Sup35.
