In 2022,Singh, Pooja S.; Ghadiyali, Mohammed; Chacko, Sajeev; Kamble, Rajesh M. published an article in Journal of Luminescence. The title of the article was 《D-A-D based pyrido-pyrazino[2,3-b]indole amines as blue-red fluorescent dyes: Photophysical, aggregation-induced emission, electrochemical and theoretical studies》.Product Details of 101-70-2 The author mentioned the following in the article:
Herein donor-acceptor-donor (D-A-D) structured, pyridopyrazino[2,3-b]indole amines 2-6 were designed and synthesized via C-N coupled Buchwald-Hartwig amination reaction and characterized by spectroscopic methods. C-N coupling in mols. offers intramol. charge transfer (ICT) transitions at longer wavelengths (λmax = 400-459 nm) in absorption spectra reminiscent D-A assembly. Dyes covers broad range of emission and emit in blue to red region with emission maxima 433-600 nm in solvent and solid film. Dyes 2, 5 and 6 explore the aggregation-induced emission (AIE) characteristics. Further C-N blending of various donor with pyridopyrazino[2,3-b]indole acceptor results in suppressed band gap (1.99-2.43 eV) and comparable HOMO (-5.17 to -5.71 eV) and LUMO (-3.18 to -3.28 eV) energies with reported small organic ambipolar materials. DFT and TDDFT calculations agree with the exptl. opto-electrochem. data. Moreover, computed small singlet and triplet excitation energy difference (ΔEST (0.01-0.14 eV)) suggest thermally activated delayed fluorescent (TADF) emitting properties of dyes. Thus pyridopyrazino[2,3-b]indole amine dyes propose their potential application in optoelectronic devices. After reading the article, we found that the author used Bis(4-methoxyphenyl)amine(cas: 101-70-2Product Details of 101-70-2)
Bis(4-methoxyphenyl)amine(cas: 101-70-2) is a diphenylamine derivative used as a chemical additive for cured rubber.Bis(4-methoxyphenyl)amine is highly toxic and may potentially induce chromosome abberation.Product Details of 101-70-2
