Usage

General Description

1,4-Phenylenebis(thiourea) is an organic compound with the chemical formula C8H10N4S2. It is commonly used as a vulcanization accelerator for rubber and plastic products. This chemical is known for its ability to significantly improve the properties of vulcanized rubber, such as increasing its tensile strength, elongation at break, and resistance to heat and aging. Additionally, 1,4-Phenylenebis(thiourea) is also used as a corrosion inhibitor in metalworking fluids and as a foaming agent in the production of foam rubber and foam plastics. However, it is important to handle this chemical with care as it is toxic if ingested and may cause skin and eye irritation upon contact.

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.

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.
