- Efficient Hole Transporting Materials with Two or Four N,N-Di(4-methoxyphenyl)aminophenyl Arms on an Ethene Unit for Perovskite Solar Cells
-
Novel steric bulky hole transporting materials (HTMs) with two or four N,N-di(4-methoxyphenyl)aminophenyl units have been synthesized. When the EtheneTTPA was used as a hole transporting material in perovskite solar cell, the power conversion efficiency a

- A mixed-valence bis(diarylamino)stilbene: Crystal structure and comparison of electronic coupling with biphenyl and tolane analogues
-
The E-4,4′-bis[di(p-anisyl)amino]stilbene cation is a class-III mixed-valence species with electronic coupling comparable to that in its biphenyl-bridged analogue, whereas its tolane-bridged analogue belongs to class II. The Royal Society of Chemistry 200

- 3,4'-Bis[bis(t-butyl- and methoxy-phenyl)amino]stilbene bis(cation radical)s and their electrochemical and magnetic properties
-
3,4'-Bis[bis(p-t-butylphenyl)amino]stilbene 1a and 3,4'-bis[bis(p- methoxyphenyl)amino]stilbene 1b were synthesized. The oxidation of 1 was analyzed by electrochemical measurements, which revealed the reversible formation of the bis(cation radical) 2 via a two-electron transfer reaction. The chemical oxidation of 1 with NOBF4 also gave the bis(cation radical) 2; UV/vis and ESR spectroscopies supported aminium radical formation without any side reaction. Magnetization, magnetic susceptibility, and the ESR ΔM(s) = ±2 signal of the biradicals indicated triplet ground states with a large triplet-singlet energy gap.
