Effect of different substituents on the fluorescence properties of precursors of synthetic GFP analogues and a polarity-sensitive lipid droplet probe with AIE properties for imaging cells and zebrafish

A series of fluorescent compounds akin to GFP precursors were designed and synthesised and the luminescence properties of the compounds were investigated by varying the substituents. We have also developed a polarity-sensitive lipid droplet probe T-LD with AIE properties
