Novel diisocyano-based dinuclear gold(I) complexes with aggregation-induced emission and mechanochromism characteristics

A series of constitutional isomers containing dinuclear gold(I) units were designed, synthesized and characterized using IR spectrometry, NMR spectroscopy and elemental analysis. The aggregation-induced emission (AIE) characteristics of the complexes were investigated by photoluminescence (PL) and UV/Vis spectroscopy. The results indicated that gold(I) complexes 1-3 exhibited significant AIE phenomena. PL spectroscopy, used to probe their solid-state mechanochromic properties, suggested ortho-isomer luminogen 1 exhibited reversible mechanochromic fluorescence, whereas meta-isomer luminogen 2 showed switchable mechanical force-induced luminescence enhancement behavior. No mechanochromism behavior was observed for para-isomer luminogen 3. Powder X-ray diffraction indicated that the morphology phase conversion between crystalline and amorphous states is responsible for the mechanochromism or mechanical force-induced emission enhancement characteristics.

Synthesis and characterization of macrocyclic compounds with a hydroxyl functional group

A novel [1+1] Schiff-base macrocyclic compound 3 has been synthesized from precursor 1, 1,3-bis(2′-formylphenoxy)-2-propanol, and precursor 2, resorcinol-bis(4-aminophenyl)ether, via condensation and cyclizaction using Ba2+ as template. The macrocycle 3 was further reduced giving saturated macrocycle 4. The structures of 3 and 4 were characterized by elemental analysis, 1H NMR, IR, and MS spectra, and their structures were determined via single crystal X-ray diffraction studies. X-ray diffraction analysis revealed that the macrocyclic compound 3 has a folded conformation, and the corresponding reduced product 4 adopts a twisted and folded conformation due to its flexible nature.

Green synthesis of symmetric aryl ether dinitro compounds in deep eutectic solvents

A series of symmetric aryl ether dinitro compounds were synthesized by 4Urea/ZnCl2 as green solvent and catalyst, and halogenated aromatic hydrocarbon derivatives and dihydroxy compounds as raw materials. This method has the advantages of easy operation, simple recrystallization, environmental friendliness and biodegradability. The structures of the products were subjected to 1H NMR, and the reaction conditions, reaction mechanism and greening advantages of deep eutectic solvents were discussed at the end of the experiments. We learned from the results of the experiments that both the aliphatic dihydroxy compounds and the aromatic dihydroxy compounds could proceed effectively in Ullmann reaction, and the desired products could be obtained in acceptable yields. When using this methodology, symmetric aryl ether dinitro compounds could be synthesized simply at 80oC in 2 h with high yields (66%~94%). Meanwhile, the DES, called deep eutectic solvent which is composed of 4Urea/ZnCl2, could be recycled at least five times without an obvious decraese in the catalytic activity.

Synthesis of novel amide derivatives with in vitro antiproliferative and cytotoxic activity

Some amide derivatives are highly valuable products with antiproliferative and cytotoxic bioactivity. In this paper, 12 novel amide compounds were synthesized correspondingly by boc-protection glycine, deprotection, and condensation reactions. The antiproliferative and cytotoxic activity of these compounds was also evaluated by human cervical cancer (Hela) and hepatoma carcinoma (SK-Hep-1) cancer cell lines. The assay revealed that eight compounds (5a-d, 6a-d) exhibited activity against Hela cancer cells. Four of them (5a-d) also showed activity against SK-Hep-1 cancer cells.

Selective monoarylation of benzenediols via dianion intermediates

Application of the SNAr reaction on benzenediols with arylfluorides revealed an enhancement in monosubstitution selectivity over bis substitution when excess base was used. This trend was studied using symmetrical and nonsymmetrical benzenediols with vari
