General Description

7-bromobenzo[c][1,2,5]thiadiazole-4-carbonitrile is a chemical compound with the molecular formula C8H3BrN2S. It is a heterocyclic aromatic compound that contains a thiadiazole ring with a bromine atom attached at the 7th position and a carbonitrile group at the 4th position. 7-bromobenzo[c][1,2,5]thiadiazole-4-carbonitrile has potential applications in the field of organic synthesis, pharmaceuticals, and materials science due to its unique structure and properties. It may be used as a building block for the synthesis of various organic compounds and may also possess biological activities that make it a potential candidate for drug development. Furthermore, its structural features make it interesting for the design and development of new materials with specific properties. However, further research is required to fully understand and exploit the potential applications of 7-bromobenzo[c][1,2,5]thiadiazole-4-carbonitrile.

Check Digit Verification of cas no

The CAS Registry Mumber 1331742-86-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,1,7,4 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1331742-86:
(9*1)+(8*3)+(7*3)+(6*1)+(5*7)+(4*4)+(3*2)+(2*8)+(1*6)=139
139 % 10 = 9
So 1331742-86-9 is a valid CAS Registry Number.

A Small Push-Pull Fluorophore for Turn-on Fluorescence

Thooft, Andrea Marie,Cassaidy, Kyle,Vanveller, Brett

, p. 8842 - 8847 (2017)

A new class of push-pull dyes is reported based on the structures of benzoxa- and benzothiadiazole heterocycles. This new class of dyes displays red-shifted wavelengths of emission and greater sensitivity to polarity and hydrogen bonding solvents relative to previously known derivatives.

Property modulation of benzodithiophene-based polymers via the incorporation of a covalently bonded novel 2,1,3-benzothiadiazole-1,2,4-oxadiazole derivative in their main chain for polymer solar cells

Agneeswari, Rajalingam,Tamilavan, Vellaiappillai,Song, Myungkwan,Hyun, Myung Ho

, p. 8515 - 8524 (2015/02/19)

Two new electron accepting monomers (BBOB and BOB) containing two serially connected different electron deficient units, such as 2,1,3-benzothiadiazole and 1,2,4-oxadiazole, were prepared and copolymerized with electron-rich benzodithiophene (BDT) derivative to afford polymers P(BDT-BBOB) and P(BDT-BOB), respectively. The optical band gaps of P(BDT-BBOB) and P(BDT-BOB) are calculated to be 2.32 eV and 1.99 eV, respectively, and their highest occupied molecular energy levels are determined to be -5.31 eV and -5.27 eV, respectively. Each of the newly synthesized polymers, i.e.P(BDT-BBOB) and P(BDT-BOB), is used as an electron donor, along with PC61BM as an electron acceptor, in the preparation of polymer solar cells (PSCs). The PSCs made with the configuration of ITO/PEDOT:PSS/P(BDT-BBOB) or P(BDT-BOB):PC61BM (1 : 2 wt%)/LiF/Al gave a maximum power conversion efficiency (PCE) of 1.76% and 2.46%, respectively, and the device performance was further improved to 3.31% and 4.21%, respectively, by simply treating the photoactive layer of PSCs with isopropyl alcohol. Overall, the opto-electrical and photovoltaic properties of the two polymers are found to be quite dependent on the configuration of the covalently bonded 2,1,3-benzothiadiazole and 1,2,4-oxadiazole units incorporated in the polymer main chain.
