Cyclobenzoins are shape-persistent macrocycles of interest in the preparation of optoelectronic and porous materials. New cyclotetrabenzoins derived from biphenyl, naphthalene, and tolane skeletons were synthesized using N-heterocyclic carbene-catalyzed b

A class of rhenium(I) tricarbonyl diimine complexes with carboxaldehyde alkynyl ligands, [Re(CO)3(N^N)(CC-C6H4-CHO)] (N^N = α,α′-diimine ligand), has been successfully synthesized and characterized, and the X-ray crystal structure of one of the complexes has been determined. Electrochemical and photophysical studies have been performed to study the effect of the variation of the diimine ligand on the redox and optical properties of the rhenium(I) complexes.

The modular synthesis of linear or cyclic multiporphyrin arrays relies on the availability of trans-substituted porphyrin building blocks with high solubility in organic solvents. Eleven porphyrin building blocks were synthesized bearing iodo, ethynyl, an

To obtain highly selective toxic derivatives of fipronil, a series of Schiff bases with an alkynyl group (3a–3k) were designed and synthesized from 4-ethynylbenzaldehyde (2) and 4-substituted 5-amino-N-arylpyrazole (1a–1k) via a nucleophilic addition elim

Cathodic photoelectrochemical (PEC) biosensors are one of ideal systems for sensing applications owing to their advantages in the low-cost, simplicity of the detection and miniaturization of the sensors with high sensitivity and specificity. Herein, a high-performance PEC sensor based on a 2D porphyrin-phthalocyanine conjugated microporous polymer (PorPc-CMP) is reported for the specific detection of H2O2 and glucose in the wide linear ranges of 0.05-100 and 0.05-5000 μM with an ultra-low limit of detection (LOD) of 13 and 27 nM, respectively. All of them achieved the best levels, when compared to H2O2 and glucose tetrapyrrole-based photoelectrochemical sensors reported so far. After a comparative analysis on the morphology, optical-electrical properties and partial charge density plots by DFT calculations for the PorPc-CMP and its analogues (PorPor-CMP and PcPc-CMP), it is revealed that the high PEC-sensing performance of PorPc-CMP is largely related to the synergistic effect of unique multi-channel D-A structure and elaborate hollow tube-like morphology, which leads to the effective charge separation, enhanced charge transportability and high utilization of light irradiation. Furthermore, good accuracy of the PorPc-CMP PEC sensor was demonstrated in real sample analysis of H2O2 disinfectant and human serum samples. This journal is
Combining photo-redox and enzyme catalysis for the synthesis of 4H-pyrimido[2,1-b] benzothiazole derivatives in one pot

A novel strategy combining visible-light and enzyme catalysis in one pot for the synthesis of 4H-pyrimido[2,1-b] benzothiazole derivatives from alcohols is described for the first time. Fourteen 4H-pyrimido[2,1-b] benzothiazole derivatives were prepared with yields of up to 98% under mild reaction conditions by a simple operation. The photoorgano catalyst rose Bengal (rB) was employed to oxyfunctionalise alcohols to aldehydes. Compared with aldehydes, alcohols with more stable properties and lower cost, thus we used photocatalysis to oxidize alcohols into aldehydes. Next, the enzyme was used to further catalyze the reaction of Biginelli to produce the target product of 4H-pyrimidine [2,1-b] benzothiazole. Experimental results show that this method provides a more efficient and eco-friendly strategy for the synthesis of 4H-pyrimido[2,1-b] benzothiazole derivatives.
CONJUGATED OLIGOMER-BASED MACROCYCLES FOR LIVE CELL IMAGING

Paragraph 0046-0047, (2020/12/29)
A phenyleneethynylene macrocycle (PEMC) is constructed that is a cyclic or polycyclic oligo (oligophenyleneethynylene-co-polyamine) where a monodispersed oligophenyleneethynylene is coupled with a polyamine. The PEMC is formed by coupling a monodispersed di-aldehyde end-capped oligophenyleneethynylene with a polyamine to form a macrocyclic imine and reducing the imine to an amine. The PEMC is useful at entering living cells for the fluorescence imaging of the living cells without toxicity to the cells.
