Check Digit Verification of cas no

The CAS Registry Mumber 4701-17-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4701-17:
(6*4)+(5*7)+(4*0)+(3*1)+(2*1)+(1*7)=71
71 % 10 = 1
So 4701-17-1 is a valid CAS Registry Number.

Synthesis and characterization of 5′-hexyl-2,2′-bithiophene based on organic dyes for dye-sensitized solar cell applications

Saravanan, Chinnusamy,Cho, Woosum,Kim, Yulhee,Jin, Sung-Ho,Gal, Yeong-Soon,Lee, Jae Wook

, p. 157 - 162 (2014)

A series of new organic dyes, 2-(2,6-bis((E)-2-(5′-hexyl-2,2′-bithiophen-5-yl)vinyl)-pyran-4-ylidene)-2-cyanoacetic acid (OD-1) and 2,2′-(2-((E)-2-(5′-hexyl-2,2′-bithiophen-5-yl)vinyl)-1H-indene-1,3(2H)-diylidene)bis(2-cyanoacetic acid) (OD-2), were synthesized as a sensitizers for the application of dye-sensitized solar cells (DSSCs). The introduction of the 5′-hexyl-2,2′-bithiophene units as an electron donor group and 2,6-dimethyl-pyran-4-one or 1,3-indandione as a π-spacers units increased the conjugation length of the sensitizers and thus improved their molar absorption coefficient and light harvesting efficiency.

Frequency and electric field controllable photodevice: FYTRONIX device

Tataro?lu,Al-Sehemi, Abdullah G.,?zdemir, Mehmet,?zdemir, Resul,Usta, Hakan,Al-Ghamdi, Ahmed A.,Farooq,Yakuphanoglu

, p. 53 - 58 (2017)

Al/p-Si/BODIPY/Al diode was fabricated by forming BODIPY organic layer on p-Si having ohmic contact. The electrical and photoresponse properties of the prepared diode were investigated in detail. The current-voltage (I-V) measurements were performed under dark and various illumination intensities. It is observed that the photocurrent under illumination is higher than the dark current. The transient measurements indicate that the device exhibits both photodiode and photocapacitor behavior. We called this device as FYTRONIX device. The photoresponse behavior of the FYTRONIX device is controlled simultaneously by frequency and electric field. The FYRONIX device can be used as a photoresponse sensor in optoelectronic applications.

Small-molecule semiconductors containing dithienylacrylonitrile for high-performance organic field-effect transistors

Li, Dizao,Zou, Jiabin,Wei, Congyuan,Zhou, Yankai,Wang, Liping,Zhang, Weifeng,Yu, Gui

, p. 11457 - 11464 (2019)

We designed and synthesized four donor-acceptor-type conjugated small-molecule compounds DPP-CN-DTE-1, DPP-CN-DTE-2, DPP-DTE-CN-1 and DPP-DTE-CN-2. The four compounds contained long alkyl side chains on the diketopyrrolopyrrole acceptor unit and cyano (CN) groups substituted on the dithiophene ethylene donor unit at different positions. The four small molecules exhibited good thermal stability and solution dispersibility. The bottom gate-bottom contact OFET devices based on these compounds showed excellent p-type performances. The relationship between molecular structures and field-effect performances indicated that the alkyl side-chain length and the CN substituted position significantly affected their charge carrier transport properties. The DPP-CN-DTE-1 with side-chain 2-mercaptotetradecyl side-chains and inner-side substituted CN groups exhibited the highest hole mobility of 2.52 cm2 V-1 s-1. This work provided a promising approach to develop excellent p-type small-molecule semiconductors with high performance, good solution processability and thermal stability for device fabrications.

A molecular breakwater-like tetrapod for organic solar cells

Yang, Jianzhong,He, Wenhan,Denman, Kimberly,Jiang, Ying-Bing,Qin, Yang

, p. 2108 - 2119 (2015/02/05)

We report the synthesis and characterization of a tetrapodal breakwater-like small molecule, SO, containing a tetraphenylsilane core and four cyanoester functionalized terthiophene arms. SO possesses a deep lying HOMO energy level of -5.2 eV and a narrow bandgap of 1.9 eV. Absorption, X-ray scattering and differential scanning calorimetry (DSC) measurements indicate crystalline nature of this compound but very slow crystallization kinetics. Solar cells employing SO and phenyl-C61-butyric acid methyl ester (PCBM) were fabricated and evaluated. Relatively low performance was obtained mainly due to the lack of optimal phase separation under various processing conditions including thermal annealing, slow-cooling and solvent annealing. Addition of poly(thienylene vinylene) (PTV), poly(3-hexylthiophene) (P3HT) and a platinum-containing low bandgap conjugated polymer Pt-BODIPY, into the SO/PCBM blend was found to induce device favorable phase separation and the polymers were found to act as the primary hole conductor. Such ternary blend devices showed cooperatively improved performances over binary devices employing either SO or the individual conjugated polymer alone.
