3-Bromo-9-(4-fluorophenyl)-9H-carbazole (cas: 922721-30-0) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Formula: C18H11BrFN

Organic light-emitting diodes (OLEDs) have great potential applications in display and solid-state lighting. Stability, cost, and blue emission are key issues governing the future of OLEDs. The synthesis and photoelectronics of 3 kinds of binaphthyl (BN) derivatives are reported. BN1-3 are melting-point-less and highly stable materials, forming very good, amorphous, glass-like films. They decompose at temperatures ≤485-545°. At a constant c.d. of 25 mA cm-2, an ITO/BN3/Al single-layer device has a much-longer lifetime (>80 h) than that of an ITO/NPB/Al single-layer device (8 h). Also, the lifetime of a multilayer device based on BN1 is longer than a similar device based on NPB. BNs are efficient and versatile OLED materials: they can be used as a hole-transport layer (HTL), a host, and a deep-blue-light-emitting material. This versatility may cut the cost of large-scale material manufacture More importantly, the deep-blue electroluminescence (emission peak at 444 nm with CIE coordinates (0.16, 0.11), 3.23 cd A-1 at 0.21 mA cm-2, and 25200 cd m-2 at 9 V) remains very stable at very high current densities up to 1000 mA cm-2. This study involved multiple reactions and reactants, such as 3-Bromo-9-(4-fluorophenyl)-9H-carbazole (cas: 922721-30-0Formula: C18H11BrFN).
