COA of Formula: C7H7I. The article was titled 《Tuning the energy level of TAPC: crystal structure and photophysical and electrochemical properties of 4,4′-(cyclohexane-1,1-diyl)bis[N,N-bis(4-methoxyphenyl)aniline]》. The information in the text is summarized as follows:
The energy level of a hole-transporting material (HTM) in organic electronics, such as organic light-emitting diodes (OLEDs) and perovskite solar cells (PSCs), is important for device efficiency. In this regard, we prepared 4,4′-(cyclohexane-1,1-diyl)bis[N,N-bis(4-methoxyphenyl)aniline] (TAPC-OMe), C46H46N2O4, to tune the energy level of 4,4′-(cyclohexane-1,1-diyl)bis[N,N-bis(4-methylphenyl)aniline] (TAPC), which is a well-known HTM commonly used in OLED applications. A systematic characterization of TAPC-OMe, including 1H and 13C NMR, elemental anal., UV-Vis absorption, fluorescence emission, d. functional theory (DFT) calculations and single-crystal X-ray diffraction, was performed. TAPC-OMe crystallized in the triclinic space group P [inline formula omitted] , with two mols. in the asym. unit. The dihedral angles between the central amine triangular planes and those of the Ph groups varied from 26.56 (9) to 60.34 (8)° due to the steric hindrance of the central cyclohexyl ring. This arrangement might be induced by weak hydrogen bonds and C-H···π(Ph) interactions in the extended structure. The emission maxima of TAPC-OMe showed a significant bathochomic shift compared to that of TAPC. A strong dependency of the oxidation potentials on the nature of the electron-donating ability of substituents was confirmed by comparing oxidation potentials with known Hammett parameters (σ). The experimental process involved the reaction of 1-Iodo-4-methylbenzene(cas: 624-31-7COA of Formula: C7H7I)
