In a document, author is Jin, Yingzhi, introduce the new discover.

Voltage losses in singlet material-based organic photovoltaic devices (OPVs) have been intensively studied, whereas, only a few investigations on triplet material-based OPVs (T-OPVs) are reported. To investigate the voltage loss in T-OPVs, two homoleptic iridium(iii) complexes based on extended pi-conjugated benzo[g]phthalazine ligands, Ir(Ftbpa)(3) and Ir(FOtbpa)(3), are synthesized as sole electron donors. T-OPVs are fabricated by mixing two donors with phenyl-C-71-butyric acid methyl ester (PC71BM) as an electron acceptor. Insertion of oxygen-bridges as flexible inert delta-spacers in Ir(FOtbpa)(3) has slightly elevated both the lowest unoccupied molecular orbital and the highest occupied molecular orbital levels compared to those of Ir(Ftbpa)(3), which results in a lower charge transfer (CT) state energy (E-CT) for Ir(FOtbpa)(3)-based devices. However, a higher V-oc (0.88 V) is observed for Ir(FOtbpa)(3)-based devices than those of Ir(Ftbpa)(3) (0.80 V). To understand the above result, the morphologies of the two blend films are studied, which excludes the influence of morphology. Furthermore, radiative and non-radiative recombination in two devices is quantitatively investigated, which suggests that a higher V-oc can be attributed to reduced radiative and non-radiative recombination loss for the Ir(FOtbpa)(3)-based devices.

In a document, author is Fallah-Ghasemi Gildeh, Sara, introduce the new discover.

Benzylation of DBU followed by anion exchange of the resulting salt with trifluoroacetate gave nearly quantitatively the ionic liquid [Bn-DBU][TFA]. It is shown here to be an efficient catalyst for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dionesviathe three-component reaction of phthalhydrazide, aromatic aldehydes, and active alpha-methylene nitriles. DFT calculations at the B3LYP/SVP level and the experimental results are in agreement with a three-step mechanism for this reaction. Based on the DFT calculations, the catalytic effect largely arises from the intrinsic ionic properties of the ionic liquid rather than its action as a simple base. These calculations also predict the existence of two close-in-energy activated complexes whose rate determining roles and energies depend on their interaction with the anionic component of the ionic liquid, as [Bn-DBU][TFA] has shown a higher catalytic activity than [Bn-DBU][OAc]. This mechanistic approach opens up new and promising insights into the rational design of ionic liquid catalysts for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones. The synthetic method presented here has several prominent advantages.

In the complex the hydrazone ligand chelates to the nickel(II) through nitrogen atoms in a bidentate manner. The antifungal activity of the ligand and its nickel(II) complex 3 was studied against Aspergillus niger, Aspergillus flavus and Candida albicans. The results revealed modest activity of the complex (3) against the tested organisms with inhibition zones of 14, 14 and 13 mm, compared to the free ligand 1 with inhibition zones of 11 mm each for A. niger, A. flavus and C. albicans respectively.
