Applications
2,9-Dimethyl-4,7-diphenyl-1,10-phenanthroline, also known as Bathocuproine (BCP), is a wide-band-gap material and has a high electron affinity. When it is embedded into organic electronic devices, bathocuproine acts as an exciton-blocking barrier which prohibits exciton diffusion process towards the Al electrode otherwise being quenched. One of the most commonly used buffer layer between acceptor and cathode layers is bathocuproine. The introduction of the buffer layer can greatly improve the PCE of polymer organic solar cells. BCP is one of the most popular hole-blocking layer materials that is used in organic electronics, including perovskite solar cells.
It was demonstrated that a BCP buffer layer reduces nonradiative recombination of excitons at the C60 –Al interface. Its most important function is to establish an Ohmic contact between the C60 film and the Al electrode in photovoltaic devices.

Check Digit Verification of cas no
The CAS Registry Mumber 4733-39-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,3 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4733-39:
(6*4)+(5*7)+(4*3)+(3*3)+(2*3)+(1*9)=95
95 % 10 = 5
So 4733-39-5 is a valid CAS Registry Number.

Ten manganese(I) tricarbonyl diimine complexes bound to variably functionalised 5-aryl-tetrazolato ligands were prepared, and their photochemical properties were investigated. Upon exposure to light at 365 nm, each complex decomposed to its free diimine and tetrazolato ligands, simultaneously dissociating three CO ligands, as evidenced by changes in the IR spectra of the irradiated complexes over time. The anti-bacterial properties of one of these complexes were tested against Escherichia coli. While the complex displayed no effect on the bacterial growth in the dark, pre-irradiated solutions inhibited bacterial growth. Comparative studies revealed that the antibacterial properties originate from the presence of free 1,10-phenanthroline.

The first examples of 4,7-disubstituted 2,9-bis(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-1,2,4-benzo-triazin-3-yl)-1,10-phenanthroline (CyMe4-BTPhen) ligands are reported herein. Evaluating the kinetics, selectivity and stoichiometry of actinide(iii) and lanthanide(iii) radiotracer extractions has provided a mechanistic insight into the extraction process. For the first time, it has been demonstrated that metal ion extraction kinetics can be modulated by backbone functionalisation and a promising new CHON compliant candidate ligand with enhanced metal ion extraction kinetics has been identified. The effects of 4,7-functionalisation on the equilibrium metal ion distribution ratios are far more pronounced than those of 5,6-functionalisation. The complexation of Cm(iii) with two of the functionalised ligands was investigated by TRLFS and, at equilibrium, species of 1?:?2 [M?:?L] stoichiometry were observed exclusively. A direct correlation between the ELUMO-EHOMO energy gap and metal ion extraction potential is reported, with DFT studies reaffirming experimental findings.
