Organic fluorophores with near-infrared (NIR) emission and reduced molecular size are crucial for advancing bioimaging biosensing technologies. Traditional methods, such as conjugation expansion heteroatom engineering, often fail to reduce fluorophore without sacrificing NIR properties. Addressing this challenge, our study utilized quantum chemical calculations structure-property relationship analysis establish an iterative design approach enable precision engineering compact, single-benzene-based fluorophores. These newly developed exhibit emissions up 759 nm maintain weights low 192 g/mol, approximately 50% of that Cy7. Additionally, they display unique environmental sensitivity─nonemissive in aqueous solutions but highly emissive lipid environments. This property significantly enhances their utility wash-free imaging live cells. Our findings mark a substantial breakthrough paving the way more efficient adaptable methodologies.

Donor–acceptor-based organic small molecules with an electronic push–pull effect can demonstrate intramolecular charge transfer to show interesting photoluminescence properties. This is essential criterion for designing fluorogenic probes cell imaging studies and the development of light-emitting diodes. Now, design such optical materials sometimes it necessary tune band gap by controlling energies highest occupied molecular orbital lowest unoccupied orbital. Typically, gaps could be modulated installing unsaturated handles between electron-rich donors electron-deficient acceptors. However, these methods are often synthetically economically challenging due involvement expensive catalysts difficult reaction setups. In our present study, we a straightforward, cost-effective method obtaining series donor–acceptor-type Vinylogous Cyano Aminoaryls (VinCAs) diverse emission colors. Further reveal that VinCAs serve as effective agents, showcasing potential use in chemical biology. Additionally, further used generate white light (WLE), showing their utility advanced lighting technologies.

Abstract Introducing two electron-donating groups and electron-withdrawing together in symmetrical positions on the benzene ring is a fundamental way to synthesize prepare single-benzene-based fluorophores (SBBFs). Their photophysical properties are adjusted through electronic structural of functional groups. Reported herein functionalization diaminobenzene derivatives with various amine protecting groups, including amides, urea, carbamates, sulfonamides. Both absorption emission obtained SBBF molecules were carefully investigated. Sequential unsymmetric diamine protections also explored for fine-tuning molecular properties.
