Three meso ‐ester boron dipyrromethene (BODIPY) dyes have been synthesized and functionalized with aggregation‐induced emission (AIE)‐active tetraphenylethene or triphenylethene moieties. It was found that functionalizing at the different positions of the BODIPY core resulted in the final dye having different emission properties in response to aggregation: from aggregation‐induced quenching (ACQ) to being AIE active. X‐ray crystallographic analysis was thus performed to provide an explanation for these differences.
