Uses
Used in Organic Field-Effect Transistors (OFETs) Industry:
Thieno[3,2-b]thiophene-2-carbonitrile is used as an intermediate for the synthesis of small molecules and polymers in the application of organic field-effect transistors (OFETs). Its electron-rich and structurally rigid properties contribute to the development of high-performance semiconducting materials for OFETs.
Used in Organic Photovoltaic Devices (OPV) Industry:
In the organic photovoltaic devices (OPV) industry, Thieno[3,2-b]thiophene-2-carbonitrile is utilized as a material for the interface layers, specifically as the hole transport layer (HTL) or electron transport layer (ETL) materials. Its extended π-conjugation and electron-rich nature enhance the efficiency and performance of OPV devices by improving charge transport and separation at the interface layers.
Check Digit Verification of cas no
The CAS Registry Mumber 40985-58-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,8 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40985-58:
(7*4)+(6*0)+(5*9)+(4*8)+(3*5)+(2*5)+(1*8)=138
138 % 10 = 8
So 40985-58-8 is a valid CAS Registry Number.

Four π-conjugated benzo[1,2-b:4,5-b′]dithiophene (BDT) based polymers were synthesized for application in polymer solar cells. These polymers possessed desirable HOMO/LUMO levels for polymer photovoltaic applications. PBDTT-TTz and PBDTT-DTBT displayed strong absorption in the range of 300-650 nm, while PBDTT-DPP and PBDTT-TTDPP showed a further 100 nm extended absorption band. The lowest unoccupied molecular orbital energy levels of polymers were tuned effectively from -3.34 eV to -3.81 eV by fusing with different accepting units. A maximum power conversion efficiency of 2.60% was obtained from photovoltaic cells with a PBDTT-TTz:PC61BM (1:2, w/w) blend film as the active layer, with a short circuit current density of 8.37 mA cm-2, an open circuit voltage of 0.70 V, and a fill factor of 44.3%.
