Description

CDT-EH-Sn, namely 4,4-Bis(2-ethylhexyl)-2,6-bis(trimethylstannyl)-4H-cyclopenta[2,1-b:3,4-b']dithiophene, is the intermediate for the synthesis of low bandgap semiconducting polymers which are widely used in OLED, OPV and OFET devices.

Check Digit Verification of cas no

The CAS Registry Mumber 920504-00-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,0,5,0 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 920504-00:
(8*9)+(7*2)+(6*0)+(5*5)+(4*0)+(3*4)+(2*0)+(1*0)=123
123 % 10 = 3
So 920504-00-3 is a valid CAS Registry Number.

Developing conjugated polymers with high electron affinity by replacing a c-c unit with a b←n unit

Dou, Chuandong,Ding, Zicheng,Zhang, Zijian,Xie, Zhiyuan,Liu, Jun,Wang, Lixiang

, p. 3648 - 3652 (2015)

The key parameters of conjugated polymers are lowest unoccupied molecular orbital (LUMO) and highest occupied molecular orbital (HOMO) energy levels. Few approaches can simultaneously lower LUMO and HOMO energy levels of conjugated polymers to a large ext

Rational design of pyrrolopyrrole-aza-BODIPY-based acceptor-donor-acceptor triads for organic photovoltaics application

Feng, Ru,Sato, Narumi,Yasuda, Takuma,Furuta, Hiroyuki,Shimizu, Soji

, p. 2975 - 2978 (2020/03/19)

Acceptor-donor-acceptor triads consisting of diketopyrrolopyrrole (DPP) or pyrrolopyrrole aza-BODIPY (PPAB) or both as acceptors and cyclopentadithiophene as a donor were rationally designed for near infrared (NIR) photovoltaics application. Among them, the PPAB-based triad exhibited the highest power conversion efficiency of 3.88% owing to the panchromatic absorption in the UV/vis/NIR regions.

Semi-transparent low-donor content organic solar cells employing cyclopentadithiophene-based conjugated molecules

Lee, Jungho,Hernandez, Jeff L.,Pelse, Ian,Reynolds, John R.,Yang, Changduk

, p. 10532 - 10537 (2018/10/24)

Considering the facile synthesis of the cyclopentadithiophene (CPDT) building block, this study aims to synthesize and characterize two donor-acceptor type conjugated molecules, 2EH-CPDT(FBTTh2)2 and 5EN-CPDT(FBTTh2)2, with different branching points from the backbone. It was found that the branching point variation strategy slightly tunes the optical and electrochemical properties of the resulting conjugated molecule films owing to the difference between their intermolecular packing. When used as a donor material in PC71BM-based organic solar cells (OSCs), the power conversion efficiency of 2EH-CPDT(FBTTh2)2 is twice that of the ones processed using 5EN-CPDT(FBTTh2)2. Interestingly, with no post treatments, OSCs were optimized with especially low-donor content within the active layer (donor:acceptor weight ratio = 1:9), which allows construction of a highly transparent film with a visible transmittance over 50%, showing potential for application in integrated photovoltaics.
