Achieving great optical anisotropy with the well-directed alignment of π-conjugated groups due to hydrogen bonds J. Saudi Chem. Soc. (IF 5.6) Pub Date : 2023-12-16 Chenhui Hu, Junjie Liu, Jiale Qu, Jinghui Hu, Xiangzhan Jiang
Looking for novel UV birefringent units with great birefringence and discovering new candidates that are constructed by them have always been a hotspot in the field of optical materials. Here, a new imidazole-based [C3N2H5]2C2O4·H2O crystal is synthesized with a cutoff edge (274 nm). According to achieve the well-directed alignment, the millimeter-sized single crystal [C3N2H5]HC2O4 is obtained and

Core-satellite nanocomposites via PEI-induced self-assembly for enhanced SERS sensing of thiram and ciprofloxacin J. Saudi Chem. Soc. (IF 5.6) Pub Date : 2023-12-15 Jiafeng He, Jumei Li
Developing sensitive, reliable, and robust surface-enhanced Raman spectroscopy (SERS) substrates relies heavily on fabricating a substantial number of hot spots. In this study, we present a straightforward method for creating Ag@PEI/Ag core-satellite nanocomposites. Large Ag nanospheres serve as the cores, and smaller Ag nanoparticles are electrostatically assembled around them through the introduction
