Special Issue Information

Dear Colleagues,

Two essential questions arise while investigating molecular structures: 1. Why are we studying molecular structures? and 2. why are we interested in studying the effects of substituents?

The answers can be most appropriately derived from the structure–property–function (SPF) relationships of molecules. These relationships associate the determined molecular structure with the physicochemical behavior of molecules.

The inclusion of hetero atoms or the addition of functional groups into molecules results in the diversification of their properties. The effect of adding substituents resembles a steering mechanism that allows researchers to manipulate the properties of the host molecules and navigate their functions. By choosing certain substituents and their placement at selected positions in molecules, we are able to a priori tailor molecular systems with certain properties according to the Lock-and-Key Principle and utilize them for large-scale applications.

The correlation between the structure of molecules and their properties and functions is a fundamental and universal principle in almost all disciplines of natural sciences. For an insightful understanding of these SPF relationships, interdisciplinary efforts ranging from chemistry, physics, biology, pharmaceutical technology, drug design, life sciences, and quantum chemistry are required.

The main objective of this Special Issue is to provide a platform for scientists who are working in the fields mentioned above and are interested in presenting their research results on the SPF relationships of molecules. Original research papers, review articles, and short communication letters are all welcome.

Two-dimensional MXenes have become an important material for electrochemical sensing of biomolecules due to their excellent electric properties, large surface area and hydrophilicity. However, the simultaneous detection of multiple biomolecules using MXene-based electrodes is still a challenge. Here, a simple solvothermal process was used to synthesis the Ti3C2Tx coated with TiO2 nanosheets (Ti3C2Tx@TiO2 NSs). The surface modification of TiO2 NSs on Ti3C2Tx can effectively reduce the self-accumulation of Ti3C2Tx and improve stability. Glassy carbon electrode was modified by Ti3C2Tx@TiO2 NSs (Ti3C2Tx@TiO2 NSs/GCE) and was able simultaneously to detect dopamine (DA), ascorbic acid (AA) and uric acid (UA). Under concentrations ranging from 200 to 1000 μM, 40 to 300 μM and 50 to 400 μM, the limit of detection (LOD) is 2.91 μM, 0.19 μM and 0.25 μM for AA, DA and UA, respectively. Furthermore, Ti3C2Tx@TiO2 NSs/GCE demonstrated remarkable stability and reliable reproducibility for the detection of AA/DA/UA. Full article
