Check Digit Verification of cas no

The CAS Registry Mumber 155166-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,1,6 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 155166-89:
(8*1)+(7*5)+(6*5)+(5*1)+(4*6)+(3*6)+(2*8)+(1*9)=145
145 % 10 = 5
So 155166-89-5 is a valid CAS Registry Number.

Improving photovoltaic properties of the linear A-Ar-A type small molecules with rhodanine by extending arylene core

Liu, Bin,Duan, Linrui,Chen, Jianhua,Duan, Xiongwei,Lei, Ting,Cai, Yufeng,Wang, Qiong,Tan, Hua,Yang, Renqiang,Zhu, Weiguo

In order to efficiently tune photovoltaic performance, a series of linear A-Ar-A type small molecules (SMs) of (DRCN3T)2Ar were designed and synthesized, which contain the same terminal of 2-(1,1-dicyanomethylene) rhodanine (DRCN) and π-bridged space of 5-vinyl-trithiophene (3T), but different central arylene (Ar) unit, respectively. Significantly extending film absorption and increasing hole mobility were obtained in these SMs with enlarging Ar units from phenylene (Ph), naphthylene (Nap) to anthrylene (Ant). As a result, photovoltaic properties were remarkably improved in these SM/PC71BM based solution-processing organic solar cells (OSCs) by enlarging Ar units in (DRCN3T)2Ar. The highest power conversion efficiency of 5.15% with a short-circuit current density of 11.34 mA cm?2 was obtained in the (DRCN3T)2Ant based device, which is three times of that in the (DRCN3T)2Ph-based device. Our work further indicates that properly extending Ar core could be beneficial to improve photovoltaic properties for the A-Ar-A type SMs.

Acceptor-donor-acceptor small molecules containing benzo [1,2-b:4,5-b′]dithiophene and rhodanine units for solution processed organic solar cells

Fan, Qunping,Li, Min,Yang, Pingao,Liu, Yu,Xiao, Manjun,Wang, Xiangdong,Tan, Hua,Wang, Yafei,Yang, Renqiang,Zhu, Weiguo

, p. 13 - 19 (2015)

Two novel solution-processed acceptor-donor-acceptor (A-D-A) structured organic molecules with 5,8-disubstituted benzo[1,2-b:4,5-b′]dithiophene (BDT or BDTT) as central and donor units, 2-(1,1-dicyanomethylene)rhodanine (DCRD) as acceptor unit and terminal group, and trithiophene (T3) as π-bridges, D(T3-DCRD)-BDT and D(T3-DCRD)-BDTT, are designed and synthesized for the application as donor materials in organic solar cells (OSCs). Both compounds exhibit broad absorption covering the wavelength range 300-750 nm and the relatively lower HOMO energy levels from -5.39 to -5.46 eV. D(T3-DCRD)-BDTT demonstrates strong absorbance and higher hole mobility than that of D(T3-DCRD)-BDT. The power conversion efficiency (PCE) values of the OSCs based on the compounds/PC61BM (1:1, w/w) are 1.10% for D(T3-DCRD)-BDT and 1.94% for D(T3-DCRD)-BDTT, under the illumination of AM. 1.5G, 100 mW/cm-2. Furthermore, the high open-circuit voltage (Voc) values are 0.93 V for D(T3-DCRD)-BDT and 0.96 V for D(T3-DCRD)-BDTT, respectively. It indicates that incorporating DCRD as an acceptor unit into D-A-D-type small molecule has proven to be promising candidates for high efficiency solution processed OSCs.
