Structure–property relationship of isomeric diphenylethenyl-disubstituted dimethoxycarbazoles
2015
Isomeric 3,6-dimethoxy- and 2,7-dimethoxycarbazoles containing diphenylethenyl moieties were synthesized by condensation of the appropriate dimethoxycarbazoles with diphenylacetaldehyde. The solid-state structures and the molecular order of the compounds were proven by X-ray crystallography. Both compounds were found to be capable of glass formation with comparable glass transition temperatures (70–71 °C). They exhibited high thermal stabilities, with the 5% weight loss temperatures exceeding 375 °C. The isomer having diphenylethenyl groups at C-3 and C-6 positions and methoxy groups at C-2 and C-7 positions (3a) exhibited aggregation-induced emission (AIE), while its counterpart having dip…
Derivatives of indandione and differently substituted triphenylamine with charge-transporting and NLO properties
2015
Abstract Derivatives containing electron-donaiting triphenylamino groups and electron-withdrawing indandione moieties were synthesized and their thermal, electrochemical, photoelectrical and nonlinear optical properties were studied. The synthesized compounds form glasses with the glass transition temperatures ranging from 69 to 118 °C. The ionization potentials of the solid samples of the synthesized materials were found to be in the range of 5.48–5.69 eV. Hole-drift mobilities estimated by xerographic time of flight technique in the amorphous layers of 2-({4-[(4-{[(2E)-1,3-dioxo-2,3-dihydro-1H-inden-2-ylidene]methyl}phenyl)(4-methoxyphenyl)amino]phenyl}methylidene)-2,3-dihydro-1H-indene-1…
Enamine-based hole transporting materials for vacuum-deposited perovskite solar cells
2020
In a short period of time, the rapid development of perovskite solar cells attracted a lot of attention in the science community with the record for power conversion efficiency being broken every year. Despite the fast progress in power conversion efficiency there are still many issues that need to be solved before starting large scale commercial applications, such as, among others, the difficult and costly synthesis and usage of toxic solvents for the deposition of hole transport materials (HTMs). We herein report new enamine-based charge transport materials obtained via a simple one step synthesis procedure, from commercially available precursors and without the use of expensive organomet…
