Description
Summary:Frontispiece: Selective quenching of the dual fluorescence from poly(fluorene) and poly(thiophene) blocks of the cationic, all‐conjugated AB diblock copolymer poly[9,9‐bis(2‐ethylhexyl)fluorene]‐b‐poly[3‐(6‐trimethylammoniumhexyl) thiophene] bromide (PF2/6‐b‐P3TMAHT) is shown to provide a sensitive and selective ratiometric method for sensing halide ions, single and double stranded DNA. It has potential for both analysis and imaging of other negatively charged species of chemical and biological interest. Further details can be found in the article by S. M. Fonseca,* R. P. Galvão, H. D. Burrows,* A. Gutacker,* U. Scherf, and G. C. Bazan on page 717.
