We have recently developed a new family of compounds, BF2-hydrazone complexes (BODIHY)1 that emit poorly in solution, but have excellent emission in the SS. This phenomenon of aggregation induced emission (AIE) was discovered in 2001 by Tang et al.,2 who proposed that aggregation restricts the rotation of (aryl) groups attached to fluorophores, hence limiting non-radiative decay pathways leading to the enhanced emission in the SS. Our highly modular and easily accessible BODIHY dyes are unique as they are the first examples of planar systems that exhibit AIE. The presentation will deal with our recent advances with these systems and our efforts in converting them into solid-state sensors.1. Y. Yang, X. Su, C. Carroll, I. Aprahamian, Chem.
