Enhanced fluorescence properties of polyfluorene-based polymer dots through an ascorbic acid-photoaging treatment for living cell imaging. Talanta 2024; 279:126628. [PMID: 39084040 DOI: 10.1016/j.talanta.2024.126628] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Revised: 07/17/2024] [Accepted: 07/27/2024] [Indexed: 08/02/2024]
Abstract
The polymer dots (Pdots) prepared by the conjugated polymer (PFO, poly (9,9-dihexylfluorene-2,7-diyl)) have high fluorescence intensity and are often used in biological fluorescence imaging. However, due to the chain defects, the PFO Pdots suffer from stability issues such as photoinactivation and photobleaching. To solve this problem, we drew inspiration from the preparation process of organic planar light-emitting devices and added an optimization processing after Pdots was prepared. We used illumination as the driving force to activate defects on its chain, and ascorbic acid as a reducing substance to restore the chain defects of the polymer to a more stable state. Through this method, we increased the fluorescence intensity by nearly 1.9 times, and significantly improving their long and short-term stability. In addition, it ensures other properties remain unchanged. This optimization scheme is also fully compatible with the entire biological imaging process, ensuring that other important properties such as cytotoxicity do not undergo unnecessary changes. Furthermore, we conducted material characterization and theoretical simulation, revealing that the optimization scheme mainly serves to repair C-9 alkyl defects on the polyfluorene unit. This study has improved and enhanced the fluorescence performance of PFO Pdots, and also provides a way to optimize the treatment of other similar conjugated polymer material systems.

Ground-state electron transfer in all-polymer donor:acceptor blends enables aqueous processing of water-insoluble conjugated polymers. Nat Commun 2023; 14:8454.

Abstract
Water-based conductive inks are vital for the sustainable manufacturing and widespread adoption of organic electronic devices. Traditional methods to produce waterborne conductive polymers involve modifying their backbone with hydrophilic side chains or using surfactants to form and stabilize aqueous nanoparticle dispersions. However, these chemical approaches are not always feasible and can lead to poor material/device performance. Here, we demonstrate that ground-state electron transfer (GSET) between donor and acceptor polymers allows the processing of water-insoluble polymers from water. This approach enables macromolecular charge-transfer salts with 10,000× higher electrical conductivities than pristine polymers, low work function, and excellent thermal/solvent stability. These waterborne conductive films have technological implications for realizing high-performance organic solar cells, with efficiency and stability superior to conventional metal oxide electron transport layers, and organic electrochemical neurons with biorealistic firing frequency. Our findings demonstrate that GSET offers a promising avenue to develop water-based conductive inks for various applications in organic electronics.
