The present invention relates to a water-soluble, simple, stable tris(N-(tert-butyl)acetamide) cyclen-based europium complex HGEu001 which exhibits the specific subcellular localization in the primary cilium with a quantum yield as high as 10% in water and a lifetime of 0.56 ms lifetime. In particular, the present invention provides simplicity of the design and synthesis of a complex. Comprehensive studies were performed in numerous cell lines, such as HeLa, SN-K-SH and MRC5; the motif structure, HGEu002, has also been synthesized as the negative control for in vitro imaging studies. The two photon in vitro imaging were done in three dimensions to emphasize on the specific localization in primary cilium of HGEu001. This is one of the very limited examples for direct primary cilium imaging.
