Rational Design of Dual-State Emission Luminogens with Solvatochromism by Combining a Partially Shared Donor–Acceptor Pattern and Twisted Structures

We report a general design strategy for a new class of luminogens with dual-state emission (DSEgens) that are brightly emissive in both the solution and solid state, with solvatochromism properties, by constructing a partially shared donor–acceptor pattern based on a twisted molecule. The DSEgens with bright fluorescence emission in both the solid and solution state demonstrate a unique solvatochromism behaviour depending on solvent polarity and thus may have applications in anti-counterfeiting.

Ni(i)-Ni(iii) cycle in Buchwald-Hartwig amination of aryl bromide mediated by NHC-ligated Ni(i) complexes

Intermediate amide complexes of NHC-ligated monovalent nickel in Buchwald-Hartwig amination of aryl halides were isolated and structurally characterized. The amide complexes reacted with aryl bromide to form a cross-coupling product. Lowerature observation of the oxidative addition product of the Ni(i) amide complex with aryl bromide indicated the presence of a Ni(iii) intermediate. The results showed that a well-defined mononuclear NHC-Ni(i) complex can act as a key intermediate in homogeneous catalysis.

Monovalent nickel complex bearing a bulky N-heterocyclic carbene catalyzes buchwaldhartwig amination of aryl halides under mild conditions

Monovalent nickel complex bearing a bulky N-heterocyclic carbene (NHC) and triphenylphosphine was synthesized and demonstrated to catalyze the BuchwaldHartwig amination of aryl halides with diarylamines to form triarylamines under mild conditions.

One to Find Them All: A General Route to Ni(I)-Phenolate Species

The past 20 years have seen an extensive implementation of nickel in homogeneous catalysis through the development of unique reactivity not easily achievable by using noble transition metals. Many catalytic cycles propose Ni(I) complexes as potential reac

Novel pypocholoride fluorescent probe of tetraphenyl ethylene borate derivative

The invention discloses a preparation method and application of a novel fluorescent probe for detecting pypocholoride. The molecular formula of the probe is C44H40BNO2, and the probe has a structure shown in the specification. The probe has weak fluorescence in a good solvent and strong green fluorescence in poor solvent water, and shows an obvious aggregation-induced emission phenomenon. The fluorescent probe shows bright green fluorescence in a PBS buffer solution, but the fluorescence is quenched after the fluorescent probe reacts with pypocholoride. After the fluorescent probe reacts with pypocholoride in a PBS buffer solution, the reaction is violent within several seconds and is stable within one minute. The fluorescent probe disclosed by the invention has excellent selectivity, ultrahigh sensitivity and shorter reaction time on detection of pypocholoride, is obvious in phenomenon, and has the effect that the probe can still recognize pypocholoride without damage in a pure water environment.

Synthesis and photochromic behaviour of a series of benzopyrans bearing an: N -phenyl-carbazole moiety: Photochromism control by the steric effect

Five new N-phenyl-carbazole benzopyrans bearing different substitutions on one of the phenyl rings at the sp3 carbon have been synthesized. Their molecular structures were investigated by X-ray and NMR analyses and through quantum chemical calculations. T

Connecting a carbonyl and a π-conjugated group through a: P-phenylene linker by (5+1) benzene ring formation

A benzene ring was formed to connect a carbonyl group of various methyl ketones with a π-conjugated group through a p-phenylene linker. Methyl ketones and streptocyanines were used as the C1 and C5 sources, respectively, in the (5+1) annulation, which could form donor-π-acceptor molecules.

Crystallization-induced phosphorescence, remarkable mechanochromism, and grinding enhanced emission of benzophenone-aromatic amine conjugates

Pure organic luminogens with efficient room temperature phosphorescence (RTP) and remarkable mechanochromism are highly desired in view of their fundamental significance and technical applications. Herein, four twisted pure organic luminogens based on ben

Catalytic carbon-nitrogen bond-forming cross-coupling using N-trimethylsilylamines

Carbon-nitrogen bond-forming cross-coupling reaction of haloarenes with N-trimethylsilyl (TMS)-substituted secondary and primary arylamines proceeded with the aid of a palladium catalyst and a fluoride activator. Various TMS-N(aryl)2, TMS-NH(aryl), and TMS-N(alkyl)2 reacted to give the corresponding coupled products in high yields. Multi-TMS-amine nucleophiles such as N,N-(TMS)2-aniline and N,N′-Ph2-N,N′-(TMS)2-p-phenylenediamine also participated in this C-N coupling to give multiply C-N coupled products in high yields. The novel C-N cross-coupling reaction was successfully applied to C-N bond-forming polymerization. Relative rates of the cross-coupling of p-bromotoluene with N-TMS-substituted primary and secondary amines showed that N-TMS-diphenylamine reacted faster than N-TMS-N-methylaniline or N-TMS-aniline, and N-TMS-morpholine was the least reactive, indicating that the low basicity of the nitrogen nucleophile is the key for the smooth coupling.
