187834-85-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 187834-85-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,8,3 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 187834-85:
(8*1)+(7*8)+(6*7)+(5*8)+(4*3)+(3*4)+(2*8)+(1*5)=191
191 % 10 = 1
So 187834-85-1 is a valid CAS Registry Number.

Enhancing Insulated Conjugated Polymer Fluorescence Quenching by Incorporating Dithia[3.3]paracyclophanes

Lillis, Ryan,Thomas, Maximillian R.,Mohanan, Manikandan,Gavvalapalli, Nagarjuna

, p. 3112 - 3119 (2021/05/05)

Insulated π-conjugated polymers exhibit enhanced chemical stability, photostability, fluorescence quantum yield, electroluminescence, solubility, and intrachain charge transport. However, insulated polymer fluorescence quenching by acceptor molecules is significantly hampered as the π-face is insulated. Photoinduced charge transfer is one of the key steps in amplified fluorescence quenching sensors and organic solar cells for charge generation. Inspired by the myelin sheath gaps in nerve cell axons, herein, we synthesized a series of insulated random copolymers of adamantanocyclophane with an increasing percentage of dithia[3.3]paracyclophane (PCP) from 5 to 30% to enhance the insulated polymer fluorescence quenching with acceptor molecules. As the percentage of the dithia[3.3]paracyclophane monomer increases, the copolymers showed an increase in absorption in the red region of the spectrum and also the copolymers' photoluminescence quantum yield reduced. The Stern-Volmer quenching constant of the 30% copolymer is ca. 4.5 times higher than that of the adamantanocyclophane homopolymer. A comparison with the control polymers indicated that the through-space-coupled interactions in PCP could be a plausible reason for the enhanced fluorescence quenching in copolymers in addition to the reduced steric hindrance by PCP. The developed copolymers combine the advantages of polymer insulation without significantly sacrificing the photoinduced charge transfer, which will help further their applicability as amplified fluorescence quenching sensors and in organic solar cells.

Facile synthesis of novel bis- and tetrakis(2-ferrocenylvinyl)[2.2]paracyclophanes by palladium-catalyzed coupling reactions

Kay, Kwang-Yol,Baek, Yong Gu,Han, Dae Won,Yeu, Sang Yong

, p. 35 - 37 (2007/10/03)

Mono-, bis-, and tetrakis(2-ferrocenylvinyl)[2.2]paracyclophanes 3,5, and 7 were synthesized by palladium-catalyzed Heck reactions of vinylferrocene (2) with mono-, bis-, and tetrakisbromosubstituted [2.2]paracyclophanes 1, 4, and 6, respectively.
