    Abstract

    A series of organic electron‐rich π‐bridged symmetric hydrazones, composed of two donor moieties connected through a thiophene‐ or a pyrrole‐based π‐spacer, has been synthesized as a suitable alternative to 2,2’,7,7’‐tetrakis[N,N‐di(4‐methoxyphenyl)amino]‐9,9’‐spirobifluorene (Spiro‐OMeTAD), considered the benchmark hole transporting material (HTM) in perovskite solar cells (PSCs). The cheap synthetic protocol is suitable for potential large‐scale production. All the compounds were characterized, showing good energy levels alignments with the perovskite and very close energy levels to the Spiro‐OMeTAD. Furthermore, computational analysis confirmed the electrochemical trend observed. The costs of synthesis were estimated, as well as the produced waste to synthesise the final HTMs, underlining the low impact of these compounds on the environment with the respect to Spiro‐OMeTAD. Overall, the relevant electrochemical properties and the low cost of the synthetic approaches allow these compounds to be a greener and easy‐to‐synthesize alternative to the Spiro‐OMeTAD for industrial development of PSCs.

    摘要 合成了一系列有机富电子π桥接对称,这些由两个通过噻吩吡咯基π间隔物连接的供体分子组成,是 2.,7.7.-四[N,N-二(4-甲氧基苯基)基]-9,9'-螺二芴(Spiro-OMeTAD)的合适替代品、2',7,7'-四[N,N-二(4-甲氧基苯基)基]-9,9'-螺二芴(Spiro-OMeTAD)的合适替代品,后者被认为是过氧化物太阳能电池(PSCs)中的基准空穴传输材料(HTM)。这种廉价的合成方案适用于潜在的大规模生产。对所有化合物都进行了表征,结果表明它们与过氧化物的能级一致,与斯派罗-OMeTAD 的能级非常接近。此外,计算分析证实了所观察到的电化学趋势。对合成成本以及合成最终 HTMs 所产生的废物进行了估算,结果表明,与螺-OMeTAD 相比,这些化合物对环境的影响较小。总之,相关的电化学特性和低成本的合成方法使这些化合物成为螺-OMeTAD 的一种更环保、更易合成的替代品,可用于 PSCs 的工业开发。
  • Isolation and Crystal Structures of Two Singlet Bis(Triarylamine) Dications with Nonquinoidal Geometries

    We report the first structural data for bis(diarylamine) "bipolarons": we have isolated and crystallographically characterized salts of the dications obtained by two-electron oxidation of E-4,4'-bis[di(p-anisyl)amino]stilbene and EE-2,5-bis4-[di(p-anisyi)amino]styryl}-3,4-di(n-butoxy)thiophene, [1](2+) and [2](2+) respectively. ESR, NMR, and magnetometry suggest both species have singlet ground states. X-ray structures, together with H-1 NMR coupling constants for [2](2+), indicate geometries in which the bond lengths are shifted toward a quinoidal pattern relative to that in the neutral species, but not to a fully quinoidal extent. In particular, the bond-length alternations across the vinylene bridging groups approach zero. DFT calculations with closed-shell singlet configurations reproduce the observed structures well. Our results indicate that singlet species for which one might expect quinoidal geometries (with differences of ca. 0.1 A between formally single and double bonds) on the basis of a limiting valence-bond representation of the structure can, in fact, show structures with significantly different patterns of bond lengths.
