Usage

General Description

1,3,6,8-Tetraphenylpyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four phenyl groups. It is a highly conjugated molecule with potential applications in organic electronic devices due to its semiconductor properties. It has been investigated for its potential use as a fluorescent material in organic light-emitting diodes (OLEDs) and as a photosensitizer in photodynamic therapy for cancer treatment. However, like other PAHs, 1,3,6,8-tetraphenylpyrene is also a known environmental pollutant and has been linked to adverse health effects, including cancer and reproductive toxicity. Therefore, its use and disposal should be carefully managed to minimize its impact on human health and the environment.

Unusual photoluminescence characteristics of tetraphenylpyrene (TPPy) in various aggregated morphologies

We found that 1,3,6,8-tetraphenylpyrene (TPPy) demonstrates unusual photoluminescence (PL) characteristics in the solid-state morphologies. We investigated the PL characteristics of TPPy in various morphologies including powder, deposited film, and soluti

Tetraphenylpyrene-bridged silsesquioxane-based fluorescent hybrid porous polymer with selective metal ions sensing and efficient phenolic pollutants adsorption activities

A silsesquioxane based fluorescent porous polymer (PCS-TPPy) was easily prepared by Friedel-Crafts reaction of tetraphenylpyrene (TPPy) with octavinylsilsesquioxane (OVS) using AlCl3 as catalyst. PCS-TPPy exhibited a high porosity with a Brunau

Solid-state Suzuki-Miyaura cross-coupling reactions: Olefin-accelerated C-C coupling using mechanochemistry

The Suzuki-Miyaura cross-coupling reaction is one of the most reliable methods for the construction of carbon-carbon bonds in solution. However, examples for the corresponding solid-state cross-coupling reactions remain scarce. Herein, we report the first broadly applicable mechanochemical protocol for a solid-state palladium-catalyzed organoboron cross-coupling reaction using an olefin additive. Compared to previous studies, the newly developed protocol shows a substantially broadened substrate scope. Our mechanistic data suggest that olefin additives might act as dispersants for the palladium-based catalyst to suppress higher aggregation of the nanoparticles, and also as stabilizer for the active monomeric Pd(0) species, thus facilitating these challenging solid-state C-C bond forming cross-coupling reactions.

Synthesis and structure of trans-bis(1,4-dimesityl-3-methyl-1,2,3-triazol- 5-ylidene)palladium(II) dichloride and diacetate. Suzuki-Miyaura coupling of polybromoarenes with high catalytic turnover efficiencies

trans-Bis(1,4-dimesityl-3-methyl-1,2,3-triazol-5-ylidene)palladium(II) dichloride has been shown to be an excellent catalyst for the multiple Suzuki-Miyaura coupling reactions of polybromoarenes to the corresponding fully substituted polyarylarenes. The reactions proceeded in excellent yields and with high turnover numbers. With 1,4-dibromobenzene the catalyst was found to be active for up to 13 consecutive cycles with a turnover number of 1260. The polyarylarenes were obtained in pure form after crystallization once without recourse to chromatographic purification. The single-crystal X-ray structures of the chloro (1) as well as the corresponding acetato (2) complexes are also reported and compared with the corresponding complexes of 1,4-diphenyl-3-methyl- 1,2,3-triazol-5-ylidene as the ligand.
