Abstract
- Abstract: Photophysical and photochemical properties of corannulene (CA) and tetrabromocorannulene (TBCA) in solution were investigated as follows. Spectra, quantum yields and lifetimes of fluorescence in solution at 295K, and spectra and lifetimes of phosphorescence in a rigid matrix at 77K were determined. Phosphorescence at 295K was observed from TBCA. Intersystem crossing yields were determined to be as large as 0.9 by optoacoustic techniques. Triplet–triplet absorption spectra were obtained by laser flash photolysis. Absorption spectra of the radical cation and anion of CA were obtained by pulse radiolysis techniques.
