Abstract

The absorption spectra of N-ethylcarbazole, 1,3-di(N-carbazolyl) propane, meso (d¢)-2,4-di(N-carbazolyl) pentane and poly(N-vinylcarbazole) in the excited singlet state were measured in solution by a picosecond Nd3+ : YAG laser photolysis method. Analyzing the absorption rise curve, the formation time constant of the sandwich excimer at room temperature is determined and discussed.
