52762-41-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52762-41-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,7,6 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 52762-41:
(7*5)+(6*2)+(5*7)+(4*6)+(3*2)+(2*4)+(1*1)=121
121 % 10 = 1
So 52762-41-1 is a valid CAS Registry Number.

3,4-Bis(1,3-benzothiazol-2-yl)furan

Mrvos-Sermek,Tralic-Kulenovic,Nagl,Fiser-Jakic

, p. 2541 - 2543 (1996)

The title compound, C18H10N2OS2, was prepared and characterized on the basis of its 1H NMR and UV spectra, and X-ray diffraction analysis. The five-membered heterocyclic rings are flat and coplanar with their fused benzene rings. The furan ring is planar, with the 2-benzothiazolyl groups rotated out of plane by 6.3 (1) and 32.7 (1)°. The S atoms of the 2-benzothiazolyl groups are positioned anti with respect to one another.

THIENO, FURO AND SELENOPHENO-[3,4-C]PYRROLE-4,6-DIONE COPOLYMERS

Paragraph 00112, (2014/03/25)

Novel photoactive copolymers based on thieno, furo or selenopheno-[3,4- c]pyrrole-4,6-dione-derivative are described herein. More specifically, the photoactive copolymers comprise repeating units of Formula I -[A1-A2]- I wherein A1 is an electron donating unit such as a mono or polycyclic heteroaryl that is unsubstitued or substituted with one or more C1-20-alkyl or C1-20-alkoxy; and A2 is an alkylfuro or alkylselenopheno-[3,4-c]pyrrole-4,6-dione-derivative. The photoactive copolymers are suitable for use in BHJ solar cells.

Thieno-, furo-, and selenopheno[3,4-c ]pyrrole-4,6-dione copolymers: Effect of the heteroatom on the electrooptical properties

Beaupre, Serge,Pron, Agnieszka,Drouin, Simon H.,Najari, Ahmed,Mercier, Lauren G.,Robitaille, Amelie,Leclerc, Mario

, p. 6906 - 6914,9 (2020/08/24)

New push-pull conjugated polymers based on furo[3,4-c]pyrrole-4,6-dione (FPD) and selenopheno[3,4-c]pyrrole-4,6-dione (SePD) have been synthesized and compared with their thieno[3,4-c]pyrrole-4,6-dione (TPD) analogues to investigate the effects of the heteroatom on the electrooptical properties. The copolymers were synthesized using either Stille cross-coupling or direct heteroarylation polymerization (DHAP), the latter method giving high molecular weights. Hypsochromic shifts of the band gaps were observed for FPD-based copolymers (sulfur substituted by oxygen) while small bathochromic shift was observed for SePD (sulfur substituted by selenium) when compared to its TPD analogue. These two new classes of conjugated polymers exhibit electrooptical properties that could lead to interesting bulk heterojunction plastic solar cells.
