The morphologies of self-assembled structures of <b>TPA </b>were studied at various concentrations in dimethyl sulphoxide (DMSO) and Tetrahydrofuran (THF). The microscopic studies through SEM and fluorescence microscopy reveal the formation of sunflower-like fluorescent self-assemblies. Further, our study revealed that the sunflower shaped assemblies formed by <b>TPA </b>exhibitfluorescence under blue, green, and red channels that can be evinced by the fluorescence spectroscopy and microscopy. Hence <b>TPA</b> exhibits panchromatic emission properties and it reveals tunable emission properties under different excitation wavelengths. Further, AIE properties of <b>TPA</b> were evinced by recording fluorescence in THF under varying concentrations of water and doing solvent chromic studies.Finally,the utility of <b>TPA</b> as a cell imaging agent was studied in human breast cancer cell lines (MDA-MB-231) which suggested <b>TPA</b> can penetrate the cell membrane and can be effectively used as a cell labeling dye.</p>
