207739-72-8 Usage

Description

Spiro-OMeTAD (Spiro-MeOTAD) is one of the most studied and suitable hole transport layer materials (HTL) due to its facile implementation and high performance in organic-inorganic electronic devices. The spiro-linked molecule provides high glass transition temperature (Tg), morphological stability and easy processability while maintaining good electronic properties. Spiro-MeOTAD has been widely used in solid-state dye-sensitised solar cells (ssDSSC), organic light-emitting dioes (OLED), perovskite solar cells (PSCs) and polymer based organic solar cells (OSCs).

Check Digit Verification of cas no

The CAS Registry Mumber 207739-72-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,7,3 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 207739-72:
(8*2)+(7*0)+(6*7)+(5*7)+(4*3)+(3*9)+(2*7)+(1*2)=148
148 % 10 = 8
So 207739-72-8 is a valid CAS Registry Number.

Similar or different: the same Spiro-core but different alkyl chains with apparently improved device performance of perovskite solar cells

Liu, Fan,Bi, Shiqing,Wang, Xiaorui,Leng, Xuanye,Han, Mengmeng,Xue, Baoda,Li, Qianqian,Zhou, Huiqiong,Li, Zhen

, p. 739 - 745 (2019)

By intelligently utilizing the odd-even effect existing in the melting points of alkanes as presented in the basic textbook of Organic Chemistry, different alkoxy groups were introduced to modify the structure of commercial Spiro-OMeTAD to give new Spiro derivatives of Spiro-OEtTAD, Spiro-OPrTAD, Spiro-OiPrTAD and Spiro-OBuTAD, with the aim to adjust the molecular packing status in perovskite solar cells as hole transporting compounds. Excitedly, with the introduction of ethoxy groups instead of the methoxy ones in Spiro-OMeTAD, Spiro-OEtTAD-based perovskite solar cells demonstrated the highest device performance of 20.16%, higher than that of Spiro-OMeTAD (18.64%).

HETEROATOMIC-BASED HOLE-TRANSPORT MATERIALS

-

Paragraph 0013, (2021/04/30)

Heteroatomic hole transport materials are provided. The hole transport materials include a non-carbon core: two, four, or eight aromatic groups covalently bound to the non-carbon core; a. terminal substituted diphenylamine end unit on each aromatic group: and optionally aromatic linker groups linking the aromatic groups and the substituted diphenylamine end units. In some embodiments the non-carbon core is non-carbon central atom such as Si, Ge, B?, P+Sn or Pb. In other embodiments, the non-carbon core is a cubic silsesquioxane. Also provided are methods for making these materials. The materials are particularly useful as hole transport materials in perovskite solar cells.
