General Description

4,6-bis(3'-(2-ethylhexyl)thien-2'-yl)thieno[3,4-c][1,2,5]thiadiazole is a chemical compound used in the production of organic electronic devices such as organic solar cells and organic field-effect transistors. It is a conjugated molecule with a thienothiadiazole core, which has been found to have high electron mobility and suitable energy levels for efficient charge transfer in electronic devices. The molecule's two thienyl units with 2-ethylhexyl substituents enhance its solubility and film-forming properties, making it a desirable material for solution-processed device fabrication. Overall, 4,6-bis(3'-(2-ethylhexyl)thien-2'-yl)thieno[3,4-c][1,2,5]thiadiazole shows promise as a semiconductor material for next-generation electronic applications.

Check Digit Verification of cas no

The CAS Registry Mumber 1314359-43-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,4,3,5 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1314359-43:
(9*1)+(8*3)+(7*1)+(6*4)+(5*3)+(4*5)+(3*9)+(2*4)+(1*3)=137
137 % 10 = 7
So 1314359-43-7 is a valid CAS Registry Number.

Low-bandgap donor-acceptor copolymers with 4,6-bis(3′-(2-ethylhexyl) thien-2′-yl)thieno[3,4-c][1,2,5]thiadiazole: Synthesis, optical, electrochemical, and photovoltaic properties

Cimrova, Vera,Kminek, Ivan,Pavlackova, Petra,Vyprachticky, Drahomir

experimental part, p. 3426 - 3436 (2012/05/05)

Two new low-bandgap alternating copolymers (CEHTF and CEHTP) consisting of 4,6-bis(3′-(2-ethylhexyl)thien-2′-yl)thieno[3,4-c][1,2,5] thiadiazole and 9,9-bis(2-ethylhexyl)fluorene or 2,5-bis(isopentyloxy)benzene were synthesized by Suzuki coupling reaction of corresponding comonomers. Their optical, electrochemical, and photovoltaic (PV) properties were studied and are reported. Both the copolymers exhibited long-wavelength absorption covering the whole visible spectral region, which is in CEHTP thin films extended up to near infrared region, ambipolar redox properties, and electrochromism. High-electron affinities and low-optical bandgap values, 1.37 and 1.15 eV, were determined for CEHTF and CEHTP, respectively. PV devices with bulk heterojunction made of blends of copolymers and fullerene derivative [6,6]-phenyl-C61- butyric acid methyl ester ([60]PCBM) were prepared and characterized. Effects of intramolecular charge transfer strength and side-chain nature and length on photophysical properties are discussed.
