Paper Abstract

The transient absorption spectrum of a nonaggregated vanadylphthalocyanine solution has been measured by a subpicosecond pump-probe spectroscopy technique. A biexponential response with time constants of 4 ps and 800 ps has been observed. The dependence of the polarizations of pump and probe light has been investigated. The parallel-to- perpendicular ratio, i.e. the ratio of transient absorption change between configurations where pump and probe polarizations are parallel and perpendicular to each other, respectively, is 4:3. This is different from the ratio in ordinary 1D molecules, reflecting the 2D character of the vanadylphthalocyanine molecule.
