Article Abstract
Benzene is the simplest and the most basic building block for the construction of π conjugated systems, which are widely used in various fields from fluorescent (FL) dyes to optoelectronic displays. However, achieving the red room-temperature phosphorescence (RTP) from single benzene is still challenging. Utilizing the p-π conjugation, herein, we report a single benzene-based push-pull system with red RTP under ambient condition. One of the phosphors shows maximum RTP peak at 585 nm, along with shoulder peaks at 545 nm, 635 nm, and 700 nm. This architecture is uniquely separate from conventional extended π-conjugated systems and minimizes the requirement for red/near-infrared (NIR) phosphors to a single benzene ring.

Molecules that exhibit excited-state intramolecular proton transfer (ESIPT) have demonstrated great promise in fluorescent probes. The electronic effect of substituents has an important influence on the ESIPT process. In this study, we investigated the effects of substituents on the ESIPT mechanism and the photophysical behavior of single-benzene fluorophore (SBF) derivatives with computational chemistry methods.

A series of 2-substituted 4H-chromen-4-ones 3a-3h containing triphenylamine or N-phenylcarbazole on the benzene ring were synthesized for the first time via the Suzuki coupling reaction. The photophysical properties of the compounds and their relationship to the structure of the compounds were investigated by methods such as spectroscopic analysis, single-crystal analysis, and theoretical calculations. The systematic results indicate that compounds 3a-3h have intramolecular charge transfer (ICT), aggregation-induced emission (AIE), and dual-state emission (DSE) effects with a wide range of fluorescence emission wavelengths (421-618 nm), showing the potential to be developed into a full-color fluorophore.

The amplification of detection signals is an important method for improving the sensitivity of electrochemical detection. This study presents an efficient strategy for preparing electrochemical catalytic materials using a simple self-assembly technique to encapsulate Fe single atoms (Fe-SAs) and Ni single atoms (Ni-SAs) in the Cu-benzene-1,3,5-tricarboxylic acid (Cu-BTC) metal-organic framework to form a Cu-BTC@FeNi-SAs catalytic system. Subsequently, Cu-BTC@FeNi-SAs was modified on the surface of a gold electrode, and sulfadiazine was used as a template to prepare a molecularly imprinted polymer (MIP) on the modified electrode.

Conventional one-dimensional gas chromatography methods for gasoline quality monitoring require separate analyses for different component classes, limiting analytical efficiency and unconventional additive detection. This study presents a comprehensive two-dimensional gas chromatography with flame ionization detection (GC × GC-FID) platform enabling simultaneous quantification of regulated components and rapid screening of unconventional additives in a single analytical run. The method achieved excellent agreement with ASTM standards and high repeatability for BTEX (benzene, toluene, ethylbenzene, and xylenes) and oxygenates in gasoline.

Emission factor data for existing heating appliances are being used to estimate achievable emission reductions with emerging heating technologies. However, the emission factors currently being used for modeling were developed prior to low-sulfur fuel standards and rely on a small number of studies, mostly focusing on steady-state operation. In this work, detailed emission measurements of typical heating equipment fired with natural gas and No.
