Article Abstract
The development of drugs and diagnostics with desirable characteristics requires smart small-molecule ligandsligands with predefined binding parameters of interaction with the target. Here, we propose a general approach for selection of such ligands from highly diverse combinatorial libraries of small molecules by methods of kinetic capillary electrophoresis (KCE). We deduct three fundamental requirements for the combinatorial library to suit the KCE-based selection of smart ligands and suggest a universal design of the library for selecting smart small-molecule ligands: every small molecule in the library is tagged with DNA that encodes the structure of the molecule. Finally, we use several DNA-tagged small molecules, which represent a hypothetical library, to prove experimentally selection of smart small-molecule ligands by the proposed approach.

Acidochromic fluorescent membranes have garnered significant research interest owing to their potential in real-time environmental monitoring and smart sensing applications. However, the rational design of membranes to optimize their structure-property interplay for enhanced acidochromic performance remains further explored. Herein, we prepared various stimulus-responsive micro/nanofibrous membranes using electrospinning technology by incorporating a fluorescent small molecule (TPECNPy-2) with thermoplastic polyurethane (TPU) to obtain specific properties.

Drug delivery based on dynamic morphological transformation represents the cutting-edge strategy at the forefront of chemotherapy, integrating individual advantages that depend on the delivery stage and spatially resolved morphology. However, developing a tumor-specific, in vivo morphologically transformable small-molecule drug delivery system to achieve enhanced drug accumulation and photodynamic therapy (PDT) efficacy remains challenging. In this study, a multifunctional PDT formulation using natural small molecules as nanocarriers is developed, combining a tumor-targeting photosensitizer and anti-angiogenic therapy.

Halogenation emerges as a key strategy to enhance the performance of organic solar cells (OSCs) by tuning molecular packing, energy levels, and charge dynamics. Here, we report three new benzo[a]phenazine-core small-molecule acceptors, namely NA5, NA6, and NA7, and systematically evaluate their photovoltaic properties in o-xylene-processed binary and ternary OSCs. Halogenation significantly strengthens intermolecular interactions, improves charge carrier mobility, and facilitates exciton dissociation, leading to a remarkable increase in binary device efficiencies from ∼2% (NA5) to over 17% (NA6, NA7).

Fused nitrogen heterocycles emerged recently as promising scaffolds for the design of small-molecule energetic materials. Herein, we present the synthetic route to a series of new furazano[3,4-][1,2,4]triazolo[4,3-]pyrazines demonstrating outstanding thermal stability (the decomposition onset above 300 °C) and low mechanical sensitivity. Moreover, a favorable combination of high crystal densities (1.
