Dinaphtho[8,1,2-abc:8',1',2'-jkl]coronene is a complex organic compound consisting of two naphthalene units fused to a coronene core. This large polycyclic aromatic hydrocarbon features a unique structure with a central coronene ring system, which is a 12-ring polycyclic aromatic hydrocarbon, connected to two naphthalene rings. The compound is characterized by its large conjugated π-system, which contributes to its electronic properties and potential applications in materials science and organic electronics. Due to its size and complexity, dinaphtho[8,1,2-abc:8',1',2'-jkl]coronene is of interest to researchers studying the properties of large aromatic systems and their potential uses in various fields.

190-47-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 190-47-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,9 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 190-47:
(5*1)+(4*9)+(3*0)+(2*4)+(1*7)=56
56 % 10 = 6
So 190-47-6 is a valid CAS Registry Number.

Effect of overcrowding on mass spectra of polycyclic aromatic hydrocarbons; Co-operative double cyclization of two methyl substituents at overcrowded positions

Ueda, Toyotoshi,Abliz, Zeper,Iwashima, Satoshi,Aoki, Junji,Takekawa, Minoru,Kan, Teru

, p. 1053 - 1056 (1988)

Mass spectra of 1,10- (2) and 3,12-dimethyltetrabenzo[de,hi,op,st]pentacene (3), and 14-methyl-5-(2-methyl-1-naphthyl)- (5) and 12-methyl-5-(4-methyl-1- naphthyl)-benzo[a]perylene (6) were investigated to elucidate the effect of methyl substitution at overcrowded positions. Compound (2) showed a very strong [M - 6]i+ peak, whereas the spectra of (3), (5), and (6), which were similar to each other, showed intense [M - 32]i+ peaks. Thus, only in the case of the overcrowded compound (2) did a cyclization reaction occur. In the case of the analogous structure (5) release from overcrowding is achieved by twisting of the ring planes. This reaction also occurred on heating (2) in quinoline.
