Asymmetrically bridged aroyl-<i>S</i>,<i>N</i>-ketene acetal-based multichromophores with aggregation-induced tunable emission

Abstract

-ketene acetals as well as linker molecules yield a library of 23 multichromophores with substitution and linker pattern-tunable emission properties. This allows control of different communication pathways between the chromophores and of aggregation-induced emission (AIE) and energy transfer (ET) properties, providing elaborate aggregation-based fluorescence switches.
