Chemists have developed a strategy using disulfide-containing small molecules to facilitate the reversible control and delivery of ribonucleic acid (RNA). A research team has developed a method that takes advantage of a chemical process called post-synthetic RNA acylation chemistry, and combined it with dynamic disulfide exchange reaction for RNA delivery and reversible control. This method provides a way to mask the RNA molecule, and researchers can potentially regulate its activity and delivery until it reaches its target site within the cell.
Researchers develop a novel design approach to achieve nonlinear photochromism using easy-to-synthesize rhodamine spirolactam derivatives Nonlinear photochromic compounds that utilize low-energy light have received significant attention. They result in enhanced contrast and spatial resolution in photochromic reactions and allow multiple photofunctions in single molecules. However, they require complex molecular design, which limits their wide applicability. Now, researchers have achieved nonlinear photochromism using low-energy light in an easily synthesized perylene-substituted rhodamine spirolactam derivative, offering a novel design approach for simpler photofunctional materials.
