Uses

Used in Illicit Drug Production:
4-Methoxy-N-(4-methoxyphenyl)-N-phenylbenzenamine is used as a precursor in the illicit production of methamphetamine, a potent central nervous system stimulant. Its use in this context is due to its chemical properties that can be manipulated to synthesize the illicit drug, contributing to its restricted status in various countries to prevent abuse and addiction.

A simple AIE-based chemosensor for highly sensitive and selective detection of Hg2+and CN?

A novel red-emitting chemosensor BCTT has been developed for the detection of Hg2+and CN?in DMF-water solution with high sensitivity and selectivity. It exhibited a ‘turn-on’ fluorescence upon binding with Hg2+based on its

Platinum-based photosensitizer with near-infrared aggregation-induced emission for synergistic photodynamic-chemo theranostics

Photodynamic therapy (PDT) is of great interest as an emerging paradigm towards cancer treatment, owing to its advantages of minimal invasiveness and low toxicity. In this work, we incorporated cisplatin into an AIE-based photosensitizer (BT) and achieved

Direct iodination of electron-deficient benzothiazoles: Rapid access to two-photon absorbing fluorophores with quadrupolar D-π-A-π-D architecture and tunable heteroaromatic core

Direct iodination of benzothiazoles under strong oxidative/acidic conditions leads to a mixture of iodinated heteroarenes with 1-2 major components, which are easily separable and which structures depend on the I2 equivalents used. Among the unexpected bu

Oxidative C-H Homocoupling of Push-Pull Benzothiazoles: An Atom-Economical Route to Highly Emissive Quadrupolar Arylamine-Functionalized 2,2′-Bibenzothiazoles with Enhanced Two-Photon Absorption

Copper(II)-catalyzed C-H/C-H coupling of dipolar 2-H-benzothiazoles end-capped with triphenylamine moieties affords highly fluorescent 2,2′-bibenzothiazoles with quadrupolar (D-π-A-π-D) architecture displaying large two-photon absorption (TPA) cross sections (543-1252 GM) in the near-infrared region. The notably higher TPA performance as compared to quadrupolar π-systems with a widely used 2,2′-bipyridine core, along with the ease of the synthesis and chelating N^N ability, makes the title biheteroaryl platform an attractive building block for a large scope of functional dyes exploiting nonlinear optical phenomena.

Optical and electrochemical effects of triarylamine inclusion to alkoxy BODIPY-based derivatives

Three new triphenylamine-BODIPY dyadsBDPT1-3have been designed and synthesized. Their optoelectronic properties were investigated, which revealed strong electronic interactions between the donor and acceptor moieties, together with high sensitivity to the inclusion of alkoxy groups. The properties of the dyads were compared with those of reference compoundsAandBDP1, which exhibit broader absorption in the visible region as a result of the inclusion of donor groups and extended conjugation of the BODIPY core. Fluorescence quenching was also observed, which was attributed to the photoinduced electron transfer, evidenced from solvatochromic measurements, quantum yields and theoretical calculations. The oxidation potentials of new compounds were found to be lower when compared with those of other BODIPY analogues with donor groups attached. The redox, computational, absorbance and emission data suggest that compoundsBDPT1-3exhibit promising properties for their application in organic photovoltaic or light emitting (optoelectronic) devices.

Photo-Electroswitchable Arylaminoazobenzenes

Azobenzenes appended with a redox-active arylamino group (redox auxiliary, RA) are prepared and shown to undergo fast, complete, and catalytic Z→E azo isomerization upon electron loss from the RA unit of the azobenzene. The RA-azo structures can be reversibly (E→Z→E)n cycled by sequential photo- and electrostimulation. Due to the robust nature of the RA?+-azo radical cation chain carrying species, initiation of electron transfer (ET) catalysis occurs at low levels (1.0-0.04 mol %) of catalytic loading and is effective even at Z-RA-azo concentrations of 10-4-10-5 M, yielding TONs (turnover numbers) of 100-2300 under such dilute conditions. The RA-azo Z→E conversion is demonstrated using chemical oxidation (redox switching), electrochemical oxidation (electro switching), and photochemical oxidation (photoredox switching). The Z→E acceleration is shown to be at least 2 × 109-fold for RA-azo 5. DFT calculations on methyl yellow suggest that a N-centered radical cation of the RA group stabilizes the Z→E N-N twist transition state of the RA?+-azo, yielding a large reduction in the barrier for RA?+-azo compared to neutral RA-azo. The RA-azo structure class has nanomechanical features that can be toggled with photo- and electrostimulation, the latter offering a quick switch for complete Z→E conversion.

Red or near-infrared light operating negative photochromism of a binaphthyl-bridged imidazole dimer

The development of red or near-infrared light (NIR) switchable photochromic molecules is required for an efficient utilization of sunlight and regulation of biological activities. While the photosensitization of photochromic molecules to red or NIR light has been achieved by a two-photon absorption process, the development of a molecule itself having sensitivity to red or NIR light has been now a challenging study. Herein, we developed an efficient molecular design for realizing red or NIR-light-responsive negative photochromism based on binaphthyl-bridged imidazole dimers. The introduction of electron-donating substituents shows the red shift of the absorption band at the visible-light region because of the contribution of a charge-transfer transition. Especially, the introduction of a di(4-methoxyphenyl)amino group (TPAOMe) and a perylenyl group largely shifts the absorption edge of the stable colored form to 900 nm. In addition, because the absorption band of one of the derivatives substituted with TPAOMe covers the whole visible-light region, the colored form shows a neutral gray color. Upon red (660 nm) or NIR-light (790 nm) irradiation, we observed the negative photochromic reaction from the stable colored form to the metastable colorless form. Therefore, the substituted binaphthyl-bridged imidazole dimers constitute the attractive photoswitches within a biological window.
