Fluorescent materials are used to investigate a biological mechanism of a cell. The fluorescence labeling, as one of the analytical techniques, is commonly used to study the structure of living cells. Organic molecules or inorganic semiconductors are currently used in these fields. However, they both have serious drawbacks. Organic molecules lose their fluorescence intensity by self-quenching and inorganic quantum dots are toxic to a bio cell. Thus, we developed a new fluorescent material to overcome these problems by using a heterocyclic structure of the excited state intramolecular proton transfer since the molecular structure showed remarkable photophysical property and anticipate it is applied in the fluorescence labeling. The organic solution is injected to the diacetylene vesicles of diameter of few 100 nm. As expected, synthesized nano assembly has the fascinating optical property.
