CO2‐DBU‐Triggered Photoredox‐Catalyzed Direct α‐C‐H Alkylation of Alcohols

open access: yesAdvanced Science, EarlyView.
An efficient photoinduced and metal‐free method is developed for direct α‐C–H monoalkylation of alcohols utilizing the CO2‐DBU system as the hydrogen bond acceptor (HBA) in the presence of H2O, allowing for selective functionalization of alcohols with a broad substrate scope.

Effect of zeolites on the alkylation of aromatics with alkanes using a Pd nanoparticle/solid acid cooperative catalytic system

open access: yesGreen Carbon
The direct alkylation of benzene with alkanes is an effective method for alkylbenzene production. Our group previously discovered that a mixture of supported Pd nanoparticles and solid acids effectively promoted the alkylation of benzene with alkanes ...

Interplay of Backbone Conformation, Morphology and Thermoelectric Properties of Benzodifuranone‐Isatin Acceptor Polymers

open access: yesAdvanced Electronic Materials, EarlyView.
Modification of polymer backbone via halogenation and comonomer selection leads to conjugated backbones of different stereoelectronic properties, thin film morphologies, and electrical characteristics. The interplay of conformational isomerism, coplanarity, backbone curvature, backbone orientation, and ordering in thin films, electrical conductivity ...

A General Strategy to Fine‐Tune Group 14 Rhodamines for Ultrahigh Signal‐to‐Noise Ratio Labeling In Vivo by Nano‐Aggregation

open access: yesAggregate, EarlyView.
Group 14 rhodamines are one of the most widely explored fluorogenic probes with high signal‐to‐noise ratio (SNR). We have boosted the SNR of group 14 rhodamines by nano‐aggregation via a novel strategy by manipulating their dynamic physical and chemical states for the first time. The ultrahigh SNR fluorescence imaging offers a fundamental understanding
