چکیده
An unprecedented example of supramolecular isomerism based on 2D hydrogen-bonded multi-component networks that leads to the preparation of different photoproducts via a topochemical transformation is reported.

Combining hydrogen bonding and metal coordination for controlling topochemical [2 + 2] cycloaddition from multi-component assemblies.
The crystal engineering of hydrogen bonded metal assemblies based on stilbene-type compounds is exploited in order to drive [2 + 2] cycloaddition in the solid state. Harmonization of hydrogen bonding and metal coordination is shown as an alternative supramolecular approach for the rational design of novel supramolecular photoreactive networks. This approach was extended to prepare five compound...

متن کاملIsomerism and Hydrogen Bonding in the Cis-enol Forms of 1-(n-pyridyl)butane-1,3-diones: A Theoretical Study
Molecular structure, isomerism, conformational stability and intramolecular hydrogen bonding (IHB) of cis-enol forms of 1-(n-pyridyl)butane-1,3-diones (nPBD) (n = 2, 3, or 4) have been investigated by means of density functional theory (DFT) calculations. Energy differences for all possible nPBD cis-enol forms of isomers with respect to the most stable form of the correspondin...
متن کاملRegioisomer-Free C4h b-Tetrakis(tert-butyl)metallo- phthalocyanines: Regioselective Synthesis and Spectral Investigations
Metal b-tetrakis(tert-butyl)phthalocyanines are the most commonly used phthalocyanines due to their high solubility, stability, and accessibility. They are commonly used as a mixture of four regioisomers, which arise due to the tert-butyl substituent on the b-position, and to the best of our knowledge, their regioselective synthesis has yet to be reported. Herein, the C4hselective synthesis of ...
