Tetrabenz[a,c,l,n]pentacene is a polycyclic aromatic hydrocarbon (PAH) consisting of five fused benzene rings, with four additional benzene rings attached to it. This large, planar molecule is known for its unique electronic properties, making it a promising candidate for organic electronics, such as organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs). Due to its extended π-conjugation system, tetrabenzo[a,c,l,n]pentacene exhibits high charge-carrier mobility and strong light absorption, which are essential for efficient charge transport and light emission in these devices. However, its synthesis is challenging, and its stability under ambient conditions is a concern, as it is prone to oxidation and degradation. Despite these challenges, ongoing research aims to improve its performance and stability, making it a potentially valuable material for future organic electronic applications.

216-07-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 216-07-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,1 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 216-07:
(5*2)+(4*1)+(3*6)+(2*0)+(1*7)=39
39 % 10 = 9
So 216-07-9 is a valid CAS Registry Number.

Thermodynamically Stable o-Quinodimethane: Synthesis, Structure, and Reactivity

Adachi, Kazuhiko,Hirose, Shunsuke,Ueda, Yasuyuki,Uekusa, Hidehiro,Hamura, Toshiyuki

, p. 3665 - 3669 (2020/12/07)

Thermal isomerization of cyclobutaphenanthrene to o-quinodimethane was investigated. Sterically congested substituents or electron-donating substituents on the four-membered ring promoted the ring-opening, affording o-quinodimethane in a relatively stable form. Isolation of the newly prepared o-quinodimethane allowed its structural elucidation and investigation of its potential reactivities. Dual [4+2] cycloaddition of an aryne and o-quinodimethane afforded tetrabenzopentacene, demonstrating the synthetic application of the isolated compound.
