Abstract:
We report the discovery and structural elucidation of four novel metal-organic frameworks (MOFs) constructed from Zn2+ nodes, Pd(II) meso-tetra(4-carboxyphenyl)porphine, and adenine linkers. Despite sharing identical molecular building units, these MOFs exhibit distinct structural topologies, including two polymorphs, and two frameworks featuring both Zn and Zn4O clusters. These MOFs display porphyrin stacking motifs connected via one-dimensional Zn-adenine chains, enabling tunable pore structures and surface areas up to 508 m2 g-1. Photophysical studies confirm that these MOFs efficiently sensitize singlet oxygen generation under light irradiation.

02:51Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

03:02Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
