Summary: Organic dye sets a benchmark for dye-sensitized solar cells (DSSCs) application. Replacing organic dyes with inorganic phases poses a significant challenge. Surface modification techniques are considered key to improving DSSC efficiency. This study investigates the use of transition metal sulfides (TMS), specifically kesterite (Cu2ZnSnS4, CZTS), as an inorganic absorber layer for DSSCs. Results show that a lower molar ratio of CZTS compared to the N719 dye produces a stable DSSC with improved power conversion efficiency and incident photon-to-current efficiency. Higher concentrations of CZTS lead to instability and reduced performance.

Summary: New anthracene-bridged organic dyes CXC12 and CXC22 are designed and synthesized for high-efficiency dye-sensitized solar cells (DSSCs) under dim light. The addition of anthracene-acetylene group in CXC dyes extends the pi-conjugation of the molecules, resulting in improved absorption and molar extinction coefficient. Among the three anthracene-based dyes, CXC22 shows the most appropriate molecular structure for light harvesting and balancing dye loading and molecular aggregation, achieving a remarkable power conversion efficiency of 37.07% under dim-light conditions.

Summary: A series of heterocyclic dimers with twisted geometries have been synthesized and their electronic structure and energy levels were studied using spectroscopic and electrochemical methods. Significant variations in triplet energy were found under different conformational demands, and lower E-T values measured in neat films were found to be reliable indicators of host/guest compatibility for OLED devices, providing new molecular design rules for obtaining high E-T materials.

Summary: In the past decade, the use of divergent 4,2':6',4''- and 3,2':6',3''-terpyridine ligands as linkers and/or nodes in extended coordination assemblies has become popular. However, only a few of the 45 isomers of terpyridine have been utilized in such structures. This overview focuses on coordination polymers and networks containing terpyridine isomers with zinc(II) and cadmium(II), examining structural details, reproducibility, and competitive product formation. A lack of systematic investigations into these systems is highlighted.

Summary: Narrow bandgap conjugated polymers are widely studied organic semiconductors, but their short excited state lifetimes limit their applications. In this study, the effect of film morphology on triplet dynamics was investigated, and Pd porphyrin sensitization was used as a strategy to change the triplet dynamics. By using transient absorption spectroscopy, it was demonstrated that the more crystalline nonsensitized polymer had a significantly longer triplet lifetime compared to amorphous polymer, and covalently incorporating Pd porphyrin further increased the triplet yield. These synthetic approaches are crucial for various fields such as organic electronics, sensors, and bioapplications.

Summary: This article describes the synthesis and characterization of two tritopic ligands containing a 2,2':6',2''-terpyridine (tpy) metal binding domain and either a 3,2':6',3''- or a 4,2':6',4''-tpy domain. The synthetic routes involved the [Pd(dppf)Cl2]-catalyzed coupling of a boronic ester-functionalized 2,2':6',2''-tpy with bromo-derivatives of 3,2':6',3''-tpy or 4,2':6',4''-tpy. The tritopic ligands preferentially bind Fe2+ ions and form iron(II) complexes with two peripheral 3,2':6',3''-tpy or 4,2':6',4''-tpy metal binding sites.

Summary: Heterocyclic dimers composed of butterfly-shaped phenothiazine and its oxidized form have been synthesized and studied. The presence of certain substituents induces a twist in the dimers. Various analytical techniques, including X-ray crystallography and optical spectroscopy, have been used to understand the relationship between oxidation state, conformational restriction, and emission mechanisms. The mixed dimer exhibits both thermally activated delayed fluorescence and room temperature phosphorescence.

Summary: Analysis of compounds with a {M(tpy)X-3} motif in the Cambridge Structural Database (CSD) reveals 17 isostructural mononuclear [M(tpy)X-3] compounds without solvent. Face-to-face p-stacking of pyridine rings and C-H3/H3' ellipsis X hydrogen bonding are equally important. The presence of bifurcated Cl ellipsis H3/H3' interactions is a recurring packing feature in compounds containing the {M(tpy)X-3} unit, complemented by Cl ellipsis H5'/H3 interactions in some cases. Octahedral [M(tpy)F-3] complexes crystallize as hydrates with strong F ellipsis H-OH hydrogen bonding dominating the crystal packing.

Summary: A critical challenge in thermally activated delayed fluorescence (TADF) is to achieve rapid and efficient electronic transitions with a narrow singlet-triplet energy gap (Delta E-ST) in a single luminophore. This study demonstrates that homoconjugation can be utilized as a viable design strategy to address this challenge. By fusing multiple luminophores across a shared triptycene core, a TADF-active iptycene with homoconjugation was produced, leading to synergistic improvements in photoluminescence quantum yield, singlet decay rate, delayed fluorescence lifetime, and intersystem crossing rate, while narrowing the Delta E-ST. This enhancement is rationalized through TD-DFT calculations considering spin-orbit coupling. The facile synthesis, ubiquity of the pyrazine motif in state-of-the-art TADF materials, and the overall performance enhancement suggest great potential for generality.
