By using picosecond transient absorption spectral measurement techniques, we have investigated photophysical properties of several monc+substituted diphenylacetylenes (DPA). The strongly temperature dependent Sz -+S, internal conversion which was reported for DPA previously was observed for methoxy-

Excited singlet-singlet absorption spectra of aromatic charge-transfer complexes have been recorded using pulsed-laser excitation. The spectra (obtained for the tetracyanobenzene-toluene, tetracyanobenzene-benzene and pyromellitlcdianhydride-mesitylene systems) are practically identical with those o
