Dinaphtho[2,1,8,7-defg:2',1',8',7'-opqr]pentacene is a complex organic compound consisting of two naphthalene units fused to a pentacene core. This molecule is characterized by its large, planar structure and exhibits unique electronic properties due to its extended π-conjugation. It is a member of the acenes family, which are polycyclic aromatic hydrocarbons with potential applications in organic electronics, such as organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The compound's chemical structure and electronic properties make it an interesting candidate for further research and development in the field of advanced materials.

Check Digit Verification of cas no

The CAS Registry Mumber 188-91-0 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 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 188-91:
(5*1)+(4*8)+(3*8)+(2*9)+(1*1)=80
80 % 10 = 0
So 188-91-0 is a valid CAS Registry Number.

The right way to self-fuse bi- and terpyrenyls to afford graphenic cutouts

Lorbach, Dominik,Wagner, Manfred,Baumgarten, Martin,Muellen, Klaus

supporting information, p. 10578 - 10580 (2013/11/06)

In this work, we subject bi- and terpyrenyls to selective fusion for formation of extended polycyclic aromatic hydrocarbons (PAHs). Connecting the pyrene units at 4-4′- or 1-4′-positions led to smooth formation of extended PAHs, achieved via cyclodehydrog
