Synthesis, characterization, and application of cationic water-soluble oligofluorenes in DNA-hybridization detection

A simple and efficient approach was developed for the synthesis of a series of cationic water-soluble oligofluorenes up to a chain length of a heptamer. Bromoalkyl-substituted fluorenyl boronic esters as the key intermediates were synthesized by using a modified Miyaura reaction. With an increasing number of repeat units (trimer to hexamer), the size-specific oligomers have shown redshifts in both the absorption and emission maxima. The emission maximum reaches the limit for the hexamer in both water and buffer solution. The quantum yields of the oligomers decreased with increased oligomer size in water. Both fluorescence quenching of the oligomers by 9,10-anthraquinone-2,6-disulfonate and the fluorescence resonance energy transfer experiments with the oligomers as the donor and fluorescein (Fl)-labeled double-stranded DNA (dsDNA-Fl) as the acceptor revealed the chain-length-dependent behavior. The Stern-Volmer quenching constant increased with the molecular size, whereas the highest donor-sensitized Fl emission was observed for the hexamer. These size-specific oligomers also served as a model to study the structure-property relationships for cationic polyfluorenes.

An ultra-highly sensitive and selective self-enhanced AIECL sensor for public security early warning in a nuclear emergencyviaa co-reactive group poisoning mechanism

The worldwide application of nuclear power has created the potential risk of a nuclear accident, which has been a challenge to public security. In nuclear leakages, I2radioisotopes would cause rapid, global pollution. Therefore, highly sensitive and selective I2sensors exhibit their significance in nuclear accident early warnings and treatments. Herein, a conjugated polymer was developed for I2vapor monitoring with an ultra-low limit of detection (LOD). This polymer, modified with a tertiary amine as a co-reactive group, exhibits aggregation-induced electrochemiluminescence (AIECL) and self-enhanced ECL behaviors. It is noteworthy that the tertiary amine also acts as I2vapor capturing and sensing groups to give a LOD of 0.13 ppt. Excellent selectivity was obtained in various interfering atmospheres. A new mechanism was discovered for designing vapor sensors, which is summarized as co-reactive group poisoning (CGP). To meet the high efficiency requirement of nuclear emergency monitoring, an I2sensor modified screen printed carbon electrode was used due to its low cost, lack of need for pretreatment and suitability for mass production. A matching upwardly photosensitive ECL dark box was further designed. This study reports ECL vapor monitoring for the first time and provides a novel strategy for early warning of a nuclear emergency, suggesting its significance in environmental and public security fields.
