Novel symmetric Schiff-base benzobisthiazole-salicylidene derivative with fluorescence turn-on behavior for detecting Pb2+ ion

A novel ligand, N2,N6-bis(2-salicylidene)benzobisthiazole (BSBBT), was designed and synthesized with an excellent yield through a facile one-step condensation eco-reaction for fluorescent detection of Pb2+ ions. BSBBT was well-characterized through FT-IR, 1H NMR, 13C NMR and XRD for inclusive study of photo-physical behaviors. From the value of aggregation induced enhanced emission (AIEE) and excited-state intramolecular proton transfer (ESIPT) properties with a large Stocks shift (160 nm), BSBBT was characterized highly emissive in DMSO/H2O (30:70, v/v) solution as well as in solid-state. BSBBT showed a strong fast response and highly selective and sensitive “turn-on” fluorescent sensing behavior for detecting Pb2+ ions in phosphate buffer solution (PBS) without any interference from other metal cations at the physiological pH (～7.4). The calculated binding constant and detection limit were 0.41 × 105 M?1 and 2.23 × 10-6 M, respectively. Density Functional Theory calculation confirmed the formation of stable BSBBT-Pb2+ complex with a lower energy gap compared to BSBBT. BSBBT is the first high-efficient luminescent benzobisthiazole-base fluorescent sensor reported so far for detecting Pb2+ ions in PBS at the physiological pH range.

Synthesis of monosubstituted thioureas by vapour digestion and mechanochemical amination of thiocarbamoyl benzotriazoles

Thiocarbamoyl benzotriazoles, as safe and easy-to-handle isothiocyanate equivalents, were quantitatively converted to N-monosubstituted thioureas by vapour digestion synthesis under an ammonia atmosphere. This simple, but timely process provided a synthetic platform that enabled the "slow" amination reaction to be successfully transformed into a rapid one aided by mechanochemical milling. The ammonium chloride/sodium carbonate equimolar mixture allowed in situ formation of ammonia under ball-milling conditions. This novel and green approach yielded aromatic and aliphatic primary thioureas in near-quantitative isolated yields with workup entirely based on using only water. In addition, the molecular and crystal structures of selected polyaromatic primary thioureas were determined from the synchrotron powder diffraction data.

A metal-free covalent organic framework as a photocatalyst for CO2reduction at low CO2concentration in a gas-solid system

A β-ketoenamine-based COF is used as a photocatalyst to convert CO2 and H2O into CO and O2 under visible-light irradiation without using additional photosensitizers and sacrificial agents in a gas-solid system. When CO2 concentration was controlled at 30.0% at 80 °C, TpBb-COF exhibited a CO production rate of 89.9 μmol g-1 h-1, which was higher than that (52.8 μmol g-1 h-1) in pure CO2, indicating that low concentrations of CO2 are conducive to the photocatalytic reduction of CO2. DFT calculations indicate that the adsorption of H2O on TpBb-COF was more preferential, which promoted the adsorption and reduction of CO2. In light of this finding, the mechanism or reaction pathway was explored. The rate equation of CO2 photocatalytic reduction was derived to correlate the association of the CO2 concentration and CO production rate, which is consistent with the experimental results and theoretical calculations.

A ruthenium porphyrin-based porous organic polymer for the hydrosilylative reduction of CO2 to formate

A ruthenium porphyrin-based porous organic polymer (POP) was synthesized, characterized, and used to reduce CO2 to a formate salt. We demonstrate that Ru-BBT-POP can be utilized to reduce CO2 to a silyl formate and then converted to potassium formate with a respectable turnover number and frequency.

Fe3O4@SiO2 nanoparticle supported ionic liquid for green synthesis of antibacterially active 1-carbamoyl-1-phenylureas in water

In the present work, we have designed a novel, heterogeneous and recyclable magnetic Br?nsted acidic ionic liquid based on 5-phenyl-1H-tetrazole. The {Fe3O4@SiO2@CH2)35-phenyl-1H-tetrazole-SO3H/Cl} ([FSTet-SO3H]Cl) was prepared via the immobilization of 5-phenyl-1H-tetrazole-bonded sulfonic acid onto the surface of silica-coated magnetic nanoparticles using 3-chloropropyltriethoxysilane as a linker. The catalyst was characterized by XRD, TEM, FESEM, EDS, TG-DTA, and FT-IR. The ability and high activity of this catalyst were demonstrated in the synthesis of 1-carbamoyl-1-phenylureas with good to excellent yields via a new, simple and one-pot procedure in aqueous media under reflux conditions. This procedure has advantages such as high yields, short reaction times, a simple methodology and work-up process, green reaction conditions, high stability, catalytic activity, and easy preparation, separation and reusability of the catalyst. The synthesis of these compounds was confirmed by FT-IR, 1H NMR, 13C NMR and CHN. In addition, we investigated the biological properties of the 1-carbamoyl-1-phenylureas as newly synthesized compounds. The described catalyst could be easily separated from the reaction mixture by additional magnetic force and reused several times without a remarkable loss of its catalytic activity and any considerable changes in the product yield and the reaction time.

Novel 4,8-benzobisthiazole copolymers and their field-effect transistor and photovoltaic applications

A series of copolymers containing the benzo[1,2-d:4,5-d′]bis(thiazole) (BBT) unit has been designed and synthesised with bisthienyl-diketopyrrolopyrrole (DPP), dithienopyrrole (DTP), benzothiadiazole (BT), benzodithiophene (BDT) or 4,4′-dialkoxybithiazole (BTz) comonomers. The resulting polymers possess a conjugation pathway that is orthogonal to the more usual substitution pathway through the 2,6-positions of the BBT unit, facilitating intramolecular non-covalent interactions between strategically placed heteroatoms of neighbouring monomer units. Such interactions enable a control over the degree of planarity through altering their number and strength, in turn allowing for tuning of the band gap. The resulting 4,8-BBT materials gave enhanced mobility in p-type organic field-effect transistors of up to 2.16 × 10-2 cm2 V-1 s-1 for pDPP2ThBBT and good solar cell performance of up to 4.45% power conversion efficiency for pBT2ThBBT.
