A series of donor-acceptor-based 6H-indolo[2,3-b]quinoxaline amine derivatives were synthesized with different donor amines. The impact of the different donor moieties on 6H-indolo[2,3-b]quinoxaline was systematically examined by absorption-emission spectroscopy, cyclic voltammetry and theor. studies. The photophys. properties of these mols., such as intramol. charge transfer transitions (400 to 462 nm) and emission (491 to 600 nm), were influenced by the nature of the peripheral amines. Further, the solid-state emission demonstrated by some of the dyes aroused our interest in performing photophys. studies on the aggregation-induced emission phenomenon; these dyes showed nanoparticle formation in THF/H2O solvent mixtures Varying the strength of the peripheral amines in the derivatives also tuned the electrochem. data, with lower band gaps (1.56 to 2.21 eV) and comparable HOMO-LUMO energy levels with reported ambipolar materials. The donor-acceptor architectures and HOMO-LUMO energies were further rationalized using DFT/TDDFT calculations Thus, the opto-electrochem. studies and high thermal stability of these mols. indicate their potential application as solid-state emissive, ambipolar materials in optoelectronic devices. The experimental process involved the reaction of Bis(4-methoxyphenyl)amine(cas: 101-70-2COA of Formula: C14H15NO2)
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.COA of Formula: C14H15NO2
