Recommanded Product: 101-70-2In 2021 ,《Tetraphenylethylene-Arylamine Derivatives as Hole Transporting Materials for Perovskite Solar Cells》 was published in ACS Applied Materials & Interfaces. The article was written by Zhang, Xianfu; Liu, Xuepeng; Ghadari, Rahim; Li, Maohui; Zhou, Zi’an; Ding, Yong; Cai, Molang; Dai, Songyuan. The article contains the following contents:
A series of hole transporting materials (HTMs) with fused tetraphenylethylene cores (9,9′-bifluorenylidene and dibenzo[g,p]chrysene) as well as different substitution positions of arylamine side arms has been designed and synthesized. A reference HTM with a non-fused tetraphenylethylene core is also prepared for a comparative study. It is noted that fused tetraphenylethylene mols. show a bathochromic spectral shift, electroneg. character, and lower reorganization energies than the non-fused ones. Furthermore, the mols. with side arms located on the meta-position on the tetraphenylethylene core in terms of a double bond exhibit a deeper HOMO level than those of the para-position-based ones whether tetraphenylethylene is fused or not. Moreover, the reorganization energies of fused meta-position-based HTMs are lower than those of para-position-based HTMs. Fused tetraphenylethylene HTMs own a better hole-extraction capability than the non-fused ones. When used in perovskite solar cells, all devices with fused tetraphenylethylene HTMs display better performance than those of the non-fused ones. The HTMs based on dibenzo[g,p]chrysene exhibit better performance than those of bifluorenylidene. Moreover, the devices with HTMs with side arms located on the meta-position on the tetraphenylethylene core display higher power conversion efficiency than those of the para-position-based ones. The results give some new insight and reference to develop ideal HTMs for perovskite solar cells. In the experiment, the researchers used Bis(4-methoxyphenyl)amine(cas: 101-70-2Recommanded Product: 101-70-2)
