In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Fine-Tuning Batch Factors of Polymer Acceptors Enables a Binary All-Polymer Solar Cell with High Efficiency of 16.11%, published in 2022-01-20, which mentions a compound: 60748-47-2, Name is PD2DBA3, Molecular C51H42O3Pd2, Formula: C51H42O3Pd2.

Random conjugated polymers, such as typical polymerized small mol. acceptors (PSMAs), concurrently suffer from the dual batch factors of mol. weights (MWs) and regioregularity, which seriously interfere with the study of the relationship between batch factors and polymer properties. Here, four isomer-free PSMAs, PA-5 and three members of a PA-6 series with low (L), medium (M), and high (H) MWs, in which 5 and 6 define linkage position throughout conjugated backbone, are designed and synthesized to clearly investigate polymer batch effects. These studies reveal that PA-6-L and PA-6-M have ignorable batch differences within deviations, which deliver comparable maximum efficiencies of 14.81% and 14.99%, resp. The PA-6-H based cell is processed from chlorobenzene with its high b.p., due to the limited solubility in other common solvents, leading to large-size phase separation during prolonged film drying process, and thereby inferior performance. In contrast, PA-5 possesses diverse absorption characteristics, and ordered crystallization, which prompts higher short-circuit c.d. and fill factor in the cell. As a result, the corresponding device realizes a photovoltaic performance of 16.11%, which is one of the best binary all-polymer solar cells in the reported literature to date. This study provides a new insight into complicated batch effects of PSMAs on device performance while avoiding cross-talk between them.

The article 《Chiral Bidentate Boryl Ligand-Enabled Iridium-Catalyzed Enantioselective Dual C-H Borylation of Ferrocenes: Reaction Development and Mechanistic Insights》 in relation to this compound, is published in ACS Catalysis. Let’s take a look at the latest research on this compound (cas:60748-47-2).

Ferrocenes with planar chirality are an important class of privileged scaffolds for diverse chiral ligands and organocatalysts. The development of efficient catalytic asym. methods under mild reaction conditions is a long-sought goal in this field. Though many transition-metal-catalyzed asym. C-H activation methods were recorded during the last decade, most of them are related to C-C bond-forming reactions. Owing to the useful attribute of the C-B bond, the authors herein report an amide-directed Ir-catalyzed enantioselective dual C-H borylation of ferrocenes. The key to the success of this transformation relies on a chiral bidentate boryl ligand and a judicious choice of a directing group. The current reaction could tolerate a vast array of functionalities, affording a variety of chiral borylated ferrocenes with good to excellent enantioselectivities (35 examples, up to 98% enantiomeric excess). The authors also demonstrated the synthetic utility by preparative-scale reaction and transformations of a borylated product. Finally, from the observed exptl. data, the authors performed DFT calculations to understand its reaction pathway and chiral induction, which reveals that Me C(sp3)-H borylation is crucial to conferring high enantioselectivity through an amplified steric effect caused by an interacted B-O fragment in the transition state.

Efficient and robust electrocatalysts for acidic Oxygen reduction reaction (ORR) is crucial for the proton exchange membrane hydrogen fuel cells. However, the current electrocatalysts suffer from the stability issues in the acidic environment during ORR. Herein, we introduce a new layer-stacked two-dimensional (2D) metal-organic framework (MOF), Co3(HADQ)2 (HADQ = 2,3,6,7,10,11-hexaamine dipyrazino quinoxaline), synthesized for the first time. This novel MOF material shows the extremely high conductivity of 8,385.744 S/m with extraordinary activity (E1/2 = 0.836 V vs. RHE, n = 3.93, and jL = 5.31 mAcm-2) and an exceptional stability (up to 20,000 cycles) as the electrocatalyst for ORR in an acidic media (pH = 0.29), outperforming most of the state of the art Metal-N-C and single-atom electrocatalysts for acidic ORR.
