要旨

The ability of bis-triazinylpyridine (BTP) molecules to complex lanthanides is well-known in solution and can be judiciously utilized to elaborate solid sensing surfaces. This was done by synthesizing a new BTP derivative and covalently anchoring it onto gold surfaces. The BTP grafting, its chemical modification and the resultant lanthanide complexation were evaluated by combining X-ray Photoelectron Spectroscopy (XPS) and Polarization Modulation-Infrared Reflection Absorption Spectroscopy (PM-IRRAS). The detection of neodynium and europium cations was measured by a Quartz Crystal Microbalance (QCM). Interestingly, when immobilized on gold, BTP appeared to show very distinct sensitivities towards Eu3+ and Nd3+. Moreover, these sensitivities could be controlled by varying the pH and/or the nitrate concentration in solution. This novel strategy, consisting of the immobilization of BTP sensing molecules, is thus very promising for sensitive and specific lanthanide detection.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
