Aggregation in carbon dots

Aggregate, Volume 3, Issue 6, December 2022., 2022
Carbon dots (CDs) has excellent photoluminescence properties. Aggregation plays an important role in both the formation of CDs and their fluorescence, yet is seldom studied in detail. This review aims to fill this knowledge gap. We first discuss how aggregation leads to the formation of different types of CDs, and the impact on morphology, luminescence,

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

Advanced Photonics Research, EarlyView.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Brønsted Acid‐Catalyzed Enantioselective and Para‐Selective Addition of Phenols to 1‐Alkynylnaphth‐2‐Ols

Advanced Synthesis &Catalysis, EarlyView.
Abstract A chiral Brønsted acid‐catalyzed synthesis of axially chiral alkenes was developed via an enantioselective and para‐selective Friedel–Crafts reaction between phenols and 1‐alkynylnaphth‐2‐ols. This methodology features an efficient hydroarylation with high functional group tolerance, complete para‐selectivity, excellent yields (up to 99%), and

Modular Synthesis of 2,3,4,6‐Tetrasubstituted Thieno[2,3‐c]furans Based on Formal [3+2] Cycloaddition Utilizing [1,2]‐Phospha‐Brook Rearrangement / Brønsted Base‐Mediated Cyclization Strategy

Advanced Synthesis &Catalysis, EarlyView.
Abstract A modular synthesis of 2,3,4,6‐tetrasubstituted thieno[2,3‐c]furans, which employs a formal [3+2] cycloaddition utilizing the [1,2]‐phospha‐Brook rearrangement and a subsequent Brønsted base‐mediated cyclization, has been established, providing an efficient access to a wide range of densely functionalized thieno[2,3‐c]furans that are otherwise

Picomolar Detection of Tau Protein Using 1D Photonic Crystal Biochips for Alzheimer's Disease Diagnosis

Advanced Sensor Research, EarlyView.
Elevated levels of Tau in cerebrospinal fluids or other body fluids are associated with the progression of Alzheimer's disease. An optical technique, based on a dual label‐free and fluorescence operation mode, is developed to detect Tau protein in both standard running buffer and cerebrospinal fluid.

Synthesis of Rhodamine TEMPO Conjugates via Isonitrile‐Based Multicomponent‐Reactions for Mitochondria‐Targeted ROS‐Detection in Cancer Cells

Advanced Sensor Research, EarlyView.
This article explores the development of rhodamine TEMPO conjugates via the Ugi‐multicomponent reaction to detect reactive oxygen species (ROS) in living cells. The sensors are highly selective for mitochondria in both cancer and normal cell lines, with fluorescence quenching and EPR spectroscopy offering precise ROS detection.
