Remote Electrostatic Effect between Octahedral Ru/Ir‐Complexes and Aromatic Micelles to Improve Their Photofunctions in Water

Angewandte Chemie, EarlyView.
The aqueous‐state encapsulation of cationic Ru(II)/Ir(III)‐complexes is efficiently demonstrated by anionic aromatic micelles via remote electrostatic interactions. The resulting host–guest composites exhibit enhanced metal‐complex‐based emission (∼3 to 10‐fold) and NIR emission through guest‐to‐guest FRET upon co‐encapsulation.

Differential degradation of petroleum hydrocarbons by Shewanella putrefaciens under aerobic and anaerobic conditions

Frontiers in Microbiology
The complexity of crude oil composition, combined with the fluctuating oxygen level in contaminated environments, poses challenges for the bioremediation of oil pollutants, because of compound-specific microbial degradation of petroleum hydrocarbons ...

Carbon-13 chemical shifts in substituted naphthalenes

, 1974
The carbon-13 n.m.r. spectra of a number of substituted naphthalenes have been determined and individual resonances assigned. Substituent effects have been deduced and compared with corresponding effects in benzene.

Rare‐Earth Multivariate Metal–Organic Frameworks: Cationic Radius Biased Compositional Control and Property Tuning

Angewandte Chemie, EarlyView.
A family of multivariate metal–organic frameworks, UoB‐116(Ln), can be prepared using up to 16 different metals, revealing the ability to tune properties through compositional control. ABSTRACT The synthesis of a multivariate metal–organic framework (MTV‐MOF) family, [Ln(DNNDI)1.5]n (UoB‐116), is reported (DNNDI: N,N'‐bis(dinicotinate)‐1,4,5,8 ...

Global emissions of polychlorinated naphthalenes from 1912 to 2050

Nature Communications
Polychlorinated naphthalenes (PCNs) are persistent organic compounds that are regulated by the Stockholm Convention. Here, we estimate historical emissions from PCN production and use (1912-1987) and unintentional emissions from 20 categories (2000-2020).

Selective acylation of oxygenated naphthalenes

, 1984
The synthesis of 1,4,5,7-teetraoxygenated naphthalenes is described, as well as their selective acylation at either C-3 or C-8 using either trifluoroacetic anhydride or acetic acid and trifluoroacetic anhydride; the potential of these reactions in the ...

Heterosubstituted or functionalized derivatives of 1- and 2-(trifluoromethyl)naphthalenes emanating from aryne adducts

, 2005
More than two dozen new CF3-substituted naphthalene derivs. were prepd. in an expedient way by employing 3- and 4-(trifluoromethyl)benzyne as the key intermediates.

To Greater Twist: A Kinetically Biased π‐Radical Cascade

Angewandte Chemie, EarlyView.
π‐Radical cascades enable step‐economic construction of complex polycyclic aromatic frameworks. In this work, we show that a multifurcating pathway can be kinetically steered toward a single, more distorted product. This counterintuitive “falling‐upward” outcome arises from an intrinsic mechanistic bias, revealing a broader dimension of control in π ...

Unveiling the Photodegradation Mechanism of Monochlorinated Naphthalenes under UV-C Irradiation: Affecting Factors Analysis, the Roles of Hydroxyl Radicals, and DFT Calculation

Molecules
Polychlorinated naphthalenes (PCNs) are a new type of persistent organic pollutant (POP) characterized by persistence, bioaccumulation, dioxin-like toxicity, and long-range atmospheric transport. Focusing on one type of PCN, monochlorinated naphthalenes (

A synthesis of trifluoromethyl-substituted naphthalenes

, 2000
Alkyl and aryl Grignard reagents add to 1-(3,4-dihydro-2H-5-pyranyl)-2,2,2-trifluoro-1-ethanone by 1,4-addition, but benzyl Grignard reagents react in good yield by 1,2-addition.
