Synthetic Route of C27H18AlN3O3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Aluminum triquinolin-8-olate, is researched, Molecular C27H18AlN3O3, CAS is 2085-33-8, about External-heater-induced negative capacitance in electronic devices. Author is Okumoto, Hajime; Tsutsui, Tetsuo.
Neg. capacitance (NC) is considered an extraordinary phenomenon although it is observed in various electronic devices. Based on device-specific properties, numerous mechanisms have been proposed for decades to explain how ordinary pos. capacitance values reach neg. values at low frequencies under a high voltage bias. In a previous study, we demonstrated that ubiquitous self-heating of devices is a source of NC in organic light-emitting diodes (OLEDs) and hole-only devices. The principal mechanism of the NC is the nonlinear coupling of the real and imaginary parts of admittance, caused by AC temperature modulation. In this study, a simple test applicable to various devices was conducted to monitor the effects of heating on capacitance. External heating by nichrome wires, rather than self-heating, induced NC, which reflected the heat transfer characteristics of the devices considered: an OLED and a Schottky barrier diode. The heating effect was shown to be a basic and common mechanism of NC, independent of device-specific electronic properties. Therefore, self-heating effects must be considered prior to exploring device-specific NC sources in electronic devices.
Although many compounds look similar to this compound(2085-33-8)Synthetic Route of C27H18AlN3O3, numerous studies have shown that this compound(SMILES:[O-]C1=C2N=CC=CC2=CC=C1.[O-]C3=C4N=CC=CC4=CC=C3.[O-]C5=C6N=CC=CC6=CC=C5.[Al+3]), has unique advantages.
