Summary: The high-temperature phase of Cu2Se, beta-Cu2Se, has attracted attention for its excellent thermoelectric efficiency. Studying the effect of strain and the possibility of n-type beta-Cu2Se is essential, with compressive strain promoting the power factor and tensile strain reducing lattice thermal conductivity. Predicted zT values for n-type and p-type beta-Cu2Se can reach 1.65 and 1.71 at 800 K respectively, and a feasible strategy to manipulate the lattice structure and carrier type is proposed through doping halogen elements.

Summary: Four kinds of isomeric dithienoporphyrins(2.1.2.1) were synthesized using two di(1H-pyrrolo-2-yl)thiophenes as building blocks and two arylaldehydes under mild acid-catalyzed conditions. The conformation and properties of the dithienoporphyrins(2.1.2.1) were investigated using various spectroscopic techniques and theoretical calculations. The incorporation of thiophene subunits resulted in a more planarized molecular structure, and the dithienoporphyrin(2.1.2.1) acted as a ligand for metal ions, leading to bent molecular conformations.

Summary: Four isomeric dithienoporphyrins (2.1.2.1) were synthesized using two di(1H-pyrrolo-2-yl)thiophenes and two arylaldehydes under mild acid-catalyzed conditions. The dithienoporphyrins (2.1.2.1) exhibited altered molecular geometry and optical and electronic properties compared to other dibenzo-/dinaphthopor-phyrins(2.1.2.1). These dithienoporphyrins(2.1.2.1) can form metal complexes with nickel(II), copper(II), and palladium(II) ions, which exhibit bent molecular conformations and are influenced by the inserted metal ions.

Summary: The rationalization for chirality transfer mechanism in supramolecular host-guest assemblies has been reported for the first time. The cyclic dimer displays a large bisignate CD couplet, while the monomeric complexes exhibit negligible CD intensity. Crystallographic characterizations demonstrate that the strong intermolecular H bonding in cyclic dimers is responsible for their stability over the linear chain.

Summary: Dinickel(II) and dicopper(II) porphyrin dimers with a long unconjugated dipyrrole bridge were synthesized. The bridge can be oxidized to form a fully pi-conjugated structure, leading to one- and two-electron-oxidized species with long-range charge/radical delocalization. This results in intense absorptions in the near-infrared region and electron paramagnetic resonance signals of a triplet state. Despite the large physical separation, the two metal centers behave as a single unit and efficiently share electrons between them.

Summary: In this study, the polymorphism of six coordinated Sn(IV)-tetrabromophenyl porphyrins with fluorine-substituted phenolate ligands was investigated. The two polymorphs, 1 alpha and 1 beta, displayed distinct properties in terms of their supramolecular architecture, axial phenolate conformations, and noncovalent interactions. The emission spectra and redox behavior also differed between 1 alpha and 1 beta.

Summary: In this study, a dinickel(ii)porphyrin dimer was used with a redox-active pyrrole-moiety placed between two Ni(ii)porphyrin centers. The two metal centers were physically separated with almost no communication between them. Upon oxidation, the dimer converted into an indolizinium-fused chlorin-porphyrin heterodimer. Furthermore, oxidations of the dimer using certain oxidants resulted in the formation of a dication diradical complex.

Summary: We report an unexpected rearrangement that leads to the formation of stable dinickel/dicopper chlorin-porphyrin dication diradical heterodimers. The bridge in these diradicals undergoes a nucleophilic attack at the beta-carbon of the porphyrin pi-cation radical, initiating the rearrangement process.

Summary: This study developed novel supramolecular structures based on a custom-designed porphyrin linker Zn(II)-5,10,15,20-tetra(4-bromo-2,6-difluorophenyl) porphyrin (Zn-BFP). The inclusion of electron-withdrawing fluorine atoms near bromine atoms increased the polarizability of the bromine atoms and their participation in halogen bonding. Three new supramolecular solids were synthesized using Zn-BFP with axial linkers nicotinic acid and 5-bromonicotinic acid, exhibiting diverse halogen bonding and hydrogen bonding motifs. The influence of fluorine atoms on the porphyrin skeleton and their participation in halogen bonding were illustrated.

Summary: This study reports a series of five- and six-coordinated Fe-porphyrins and investigates the effects of non-covalent interactions on the out-of-plane displacement and spin states of iron, as well as the orientation of axial ligands. The results show that weak hydrogen bonding interactions result in elongation of Fe-O bonds and stabilization of the mixed spin state of iron. Additionally, the movement of axial ligands is restricted by strong pi-interactions. This study provides important insights into the functioning of hemoproteins such as hemoglobin.

Summary: Here, we demonstrate the chiral guest-induced contraction, extension, and twisting motions in a flexible and nano-sized achiral trizinc(ii)porphyrin trimer host. The formation of 1:1, 1:2, and 1:4 host-guest supramolecular complexes leads to the induction, inversion, and amplification, as well as reduction, of porphyrin CD responses in a single molecular framework. The opposite CD signs observed in R and S substrates suggest that chirality is solely determined by the stereographic projection of the chiral center. Additionally, the trisignate CD signals generated by long-range electronic communications between the three porphyrin rings provide further insights into molecular structures.

Summary: A highly flexible pyrrole-bridged Zn(ii)porphyrin dimer has been used as an efficient host to accurately determine the absolute configuration of a large number of chiral amino alcohols and 1,2-diols. The addition of substrates leads to the formation of 1:1 and 1:2 host-guest complexes, with the endo-endo conformation being stabilized by strong interligand H-bonds. Spectroscopic and structural studies have provided a systematic understanding of the optical activity and allowed for the determination of absolute stereochemistry in a variety of chiral substrates.
