Pyreno[1,2-b]thiophene is a heterocyclic aromatic compound consisting of a pyrene core fused with a thiophene ring. It is characterized by its unique molecular structure, which features a large π-conjugated system that extends across the pyrene and thiophene units. This extensive conjugation endows pyreno[1,2-b]thiophene with interesting electronic and optical properties, making it a potential candidate for applications in organic electronics, such as organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs). The compound's chemical structure also allows for various functionalization and modification possibilities, which can further tailor its properties for specific applications.

189-83-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 189-83-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,8 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 189-83:
(5*1)+(4*8)+(3*9)+(2*8)+(1*3)=83
83 % 10 = 3
So 189-83-3 is a valid CAS Registry Number.

Thiophene end-capped aromatic analogues, that is, naphthothiophenes, naphthodithiophenes, pyrenothiophene, and benzotrithiophene, can be prepared from commercially available hydroxyarenes in two steps, including (1) a consecutive acid-mediated nucleophilic aromatic substitution of hydroxyarenes with 2-mercaptoethanol, followed by cyclization to form an arene-fused dihydrothiophene, and (2) oxidation of the dihydrothiophene unit to thiophene.
