Octacene is a polycyclic aromatic hydrocarbon (PAH) consisting of eight linearly fused benzene rings, making it an allotrope of carbon. It is a planar, rectangular-shaped molecule with a molecular formula of C32H16. Octacene is known for its potential applications in organic electronics, such as organic solar cells and field-effect transistors, due to its unique electronic properties. However, it is challenging to synthesize and purify, and its stability is a concern for practical applications. Despite these challenges, research into octacene and its derivatives continues to explore their potential in various fields.

258-33-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 258-33-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,5 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 258-33:
(5*2)+(4*5)+(3*8)+(2*3)+(1*3)=63
63 % 10 = 3
So 258-33-3 is a valid CAS Registry Number.

Higher Acenes by On-Surface Dehydrogenation: From Heptacene to Undecacene

Zuzak, Rafal,Dorel, Ruth,Kolmer, Marek,Szymonski, Marek,Godlewski, Szymon,Echavarren, Antonio M.

, p. 10500 - 10505 (2018)

A unified approach to the synthesis of the series of higher acenes up to previously unreported undecacene has been developed through the on-surface dehydrogenation of partially saturated precursors. These molecules could be converted into the parent acenes by both atomic manipulation with the tip of a scanning tunneling and atomic force microscope (STM/AFM) as well as by on-surface annealing. The structure of the generated acenes has been visualized by high-resolution non-contact AFM imaging and the evolution of the transport gap with the increase of the number of fused benzene rings has been determined on the basis of scanning tunneling spectroscopy (STS) measurements.
