During last decade, ‘fluorescence chemosensor’ has received tremendous interest, and has become an specific subject in the field of chemistry. In particular, detecting biologically important analytes such as biothiols or ROS with fluorescence chemosensors was widely studied. Chemosensor could detect endogenous analytes with high selectivity and sensitivity, and also it has the merit of being easily-visualized. Also, photosensitizers, based on phosphorescence, also have received huge interest and widely exposure in the applications of OLED, photocatalyst, or solar cell research. In particular, in OLED research, the research of triplet excited state to produce the fluorescence from a singlet excited state was studied in worldwide laboratories, however, still it is required to develop photosensitizers which have highly energy transfer efficiency, heavy atoms which are reactive, or soluble in polar solvents. Chapter 1 introduces the general introduction of fluorescence and phosphorescence, and also features background on the simple detecting method of chemosensors. Chapter 2 introduces the new chemosensor which can selectively detect cysteine over other biothiols, and the methacrylate group with a mycophenolic acid core was used. In chapter 3, research of developing a new organic photosensitizer for triplet-triplet annihilation upconversion is described. Chapter 4 analyzes the phosphorescence of Au-corroles, and study the delayed fluorescence and room temperature phosphorescence. It is both an experimental study and a computational study.
