Enhancing Optoelectronic Properties in Phthalocyanine‐Based SURMOFs: Synthesis of ABAB Linkers by Avoiding Statistical Condensation with Tailored Building Blocks

Advanced Functional Materials, EarlyView.
A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.

Structure Elucidation of Antibiotics

2022
To date, there are hundreds of characterized natural products with antibacterial activity against pathogenic bacteria, and several have become bonafide antibiotic drugs. The development of antibacterial natural products into antibiotic drugs, both in the past and in the future, hinges upon an accurate description of the exact chemical structure of the ...

The Structure Elucidation of Pseudothiocolchicine

Helvetica Chimica Acta, 1985
AbstractA colchicine derivative, previously isolated from the reaction of isocolchicine with sodium thiomethoxide in aqueous MeOH, was now identified as 11‐(methylthio)isocolchicine on the basis of 1H‐, 13C‐NMR spectra and chemical correlation. This reaction represents the first example of abnormal nucleophilic displacement (telesubstitution) in the ...

Structural Elucidation of Complex Carbohydrates

1988
Many current problems in immunology depend on a detailed understanding of oligosaccharide and glycoconjugate structures. In contrast to other biopolymers, oligosaccharides do not have well established and sensitive analytical procedures for the determination of their structures.

Computer-Assisted Structure Elucidation

2007
This article describes NMR approaches to determine the molecular structure of a small organic molecule. The use of one- and two-dimensional spectra is described. The proton and carbon shifts determined are used to identify the best molecular matches among more than 30 million PubChem structures. Molecular carbon skeletons can be generated from 2-D homo-
