General Description

4,9-Dibromonaphtho[2,3-c][1,2,5]thiadiazole is a chemical compound composed of a naphthothiadiazole core with two bromine atoms attached at the 4th and 9th positions. 4,9-Dibromonaphtho[2,3-c][1,2,5]thiadiazole is commonly used as a building block in the synthesis of organic semiconductors and materials for electronic devices such as organic photovoltaic cells and organic field-effect transistors. Its unique structure allows for efficient electron transport and good photovoltaic performance, making it a promising candidate for use in the development of high-performance optoelectronic devices. Additionally, its relatively simple synthesis and functionalization make it a valuable tool for researchers in the field of organic electronics.

Check Digit Verification of cas no

The CAS Registry Mumber 18557-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,5 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18557-22:
(7*1)+(6*8)+(5*5)+(4*5)+(3*7)+(2*2)+(1*2)=127
127 % 10 = 7
So 18557-22-7 is a valid CAS Registry Number.

Extension of N-Heteroacenes through a Four-Membered Ring

Yang, Shuaijun,Shan, Bowen,Xu, Xiaomin,Miao, Qian

, p. 6637 - 6642 (2016)

The synthesis of novel π-extended N-heteroacenes, which have a large tetraazaacene subunit and a quinoxaline subunit connected through a four-membered ring, is reported. They were studied with experimental and computational methods in comparison to the corresponding tetraazaacenes. As found from the DFT calculation, the four-membered ring is a better linker than a five-membered ring or a C-C single bond to extend N-heteroacenes for a new design of n-type semiconductors in terms of the spatial delocalization and energy level of LUMO as well as the reorganization energy. In solution-processed thin film transistors, the π-extended N-heteroacenes are found to function as n-type semiconductors with field effect mobility of up to 0.02?cm2 V-1 s-1 under ambient conditions. Gang of four: This study demonstrates that N-heteroacenes can be extended through a four-membered ring into linear polycyclic frameworks with up to eight fused rings. It was found that the four-membered ring is a useful linker to extend electron delocalization for n-type organic semiconductors.
