A Fresh Perspective on the Internal Plasticizing Effect in Non-Polymeric Glass-Formers Open
The internal plasticizing effect occurs when a flexible substituent, especially one linked to a rigid moiety, lowers the glass transition temperature (Tg) of an organic compound by disrupting molecular packing and increasing the internal m…

A continuous flow generator of acetyl nitrate for the synthesis of nitrofuran-based pharmaceuticals Open
Nitrofurfural is a key building block for the synthesis of antimicrobial nitrofurans as active pharmaceutical ingredients. Its synthesis involves the nitration of furfural, a substrate derived from biobased resources. However, furfural has…

Normal-to-Supercooled Liquid Transition in Molecular Glass-Formers: A Hidden Structural Transformation Fuelled by Conformational Interconversion Open
Molecular dynamics and transport coefficients change significantly around the so-called Arrhenius crossover in glass-forming systems. In this article, we revisit the dynamic processes occurring in a glass-forming macrocyclic crown thiaethe…

Simple Donor–π–Acceptor Compounds Exhibiting Aggregation-Induced Emission as Hidden Fingerprints Detecting Agents Open
Latent fingerprints are a significant carrier of information for a court expert. To detect this type of forensic trace, what is necessary is a method that is easy to use, compact, and versatile. The research aimed to investigate the physic…

The Role of Intermolecular Interaction on Aggregation-Induced Emission Phenomenon and OLED Performance Open
In this work, the role of intermolecular interaction on the aggregation-induced emission (AIE) phenomenon and organic light-emitting diodes’ (OLEDs) performance was investigated. During the research, a group of compounds consisting of the …
