Luminescence and Fluorescent Materials

Fluorene-based compounds have attracted considerable attention in recent years due to their diverse biological activities and rich photophysical properties. In this study, a thiophene-containing fluorene derivative was synthesized and structurally characterized by ¹H-NMR, ¹³C-NMR, FT-IR, and GC-MS spectroscopic techni…

There are challenges in the development of organic light-emitting diode (OLED) technologies that aim to develop highly efficient, cost-effective, and stable blue thermally activated delayed fluorescent (TADF) emitters. This computational chemistry study presents a comprehensive theoretical investigation of the photoph…

Abstract This work presents an experimental and theoretical study of an aromatic nitrogen-containing ligand and its halotin complex, aiming to link molecular structure, interactions and nonlinear optical (NLO) properties. The geometries obtained from X-ray diffraction and DFT calculations are consistent, and the UV‑vi…

ABSTRACT Mechanoluminescent materials offer unique opportunities for power‐free light‐emission systems, however, pushing mechanoluminescent performance to its intrinsic limit remains a critical challenge for reliable identification under bright ambient lighting. Here, we rationally tune dipolar ligand‐assisted interfa…

Abstract The structural, electronic, and optical properties of the D- π -A chromophore 3-(4-methoxyphenyl)-2-(3-(trifluoromethyl)phenyl)acrylonitrile (MTFMAN) were comprehensively investigated using a multiscale approach combining single crystal X-ray diffraction, UV–Vis spectroscopy, and Density Functional Theory (DF…

2D colloidal nanoplatelets (NPLs) are highly attractive for light-emitting devices (LEDs) due to their thickness-dependent electronic structure and distinct excitonic properties. However, most heterostructured core/shell NPLs predominantly emit in the red spectral region and extending their emission toward shorter wav…

A new rhodamine B-based Schiff base (RSB) derivative was successfully synthesized via condensation of rhodamine B hydrazide with 5-bromo-2-hydroxybenzaldehyde and characterized using FT-IR spectroscopy, NMR, single-crystal X-ray diffraction, photophysical studies and in silico ADME analysis. FT-IR data confirmed the f…

Conjugated polymers are promising for optoelectronic applications but suffer from aggregation-caused quenching (ACQ) in the solid state. We demonstrate that incorporating amine-based additives polyethylenimine (PEI), ethylenediamine (EDA), N-methylpyrrolidone (NMP), dimethylpiperazine (DMP), and 1-methylimidazole (1MI…
