Quaterphenyl, also known as 4'',1''-quaterphenyl, is an organic compound with the chemical formula C42H26. It is a polycyclic aromatic hydrocarbon (PAH) consisting of four linearly fused benzene rings, with the fourth ring connected to the first ring at the 4'' and 1'' positions. 4'',1''']quaterphenyl is characterized by its planar structure and high symmetry, which contribute to its unique electronic and optical properties. Quaterphenyl is of interest in the field of organic electronics, particularly in the development of materials for organic light-emitting diodes (OLEDs) and organic solar cells, due to its potential to enhance charge transport and light emission. However, it is important to note that quaterphenyl, like other PAHs, may have potential health and environmental concerns due to its carcinogenic properties, and thus its use is subject to strict regulations and safety considerations.

1770-82-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1770-82-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,7 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1770-82:
(6*1)+(5*7)+(4*7)+(3*0)+(2*8)+(1*2)=87
87 % 10 = 7
So 1770-82-7 is a valid CAS Registry Number.

Bridged Organosilane and Production Method Thereof

-

Page/Page column 29-30, (2009/04/24)

Provided is a bridged organosilane, which has a large complex organic group, and which is useful in the synthesis of a mesoporous silica and a light-emitting material, and a production method of the bridged organosilane. The bridged organosilane is expressed by the following general formula (1): [in the formula (1), q represents an integer in a range from 2 to 4, X1— represents a substituent selected from the group consisting of substituents expressed by the following general formulae (2) to (5): (in the formulae (2) to (5), R1 represents alkyl group having 1 to 5 carbon atoms, R2 represents an allyl group, and n represents an integer in a range from 0 to 3, and m represents an integer in a range from 0 to 6), and A1 represents an organic group expressed by, for example, the following general formula (6): (in the formula (6), Y1 represents a substituent expressed by, for example, O═C)].
