Abstract

Femtosecond degenerate pump-probe spectroscopy was carried out on thin films of a series of axially substituted phthalocyanines including tBu₄PcInCl(tBu₄ = tetra-(tert-butyl)), tBu₄PcTiO, tBu₄PcIn(p-TMP) [p-TMP = p-trifluoromethylphenyl], tBu₄PcGa(p-CPO) [p-CPO = p-chlorophenoxy], and μ-oxo-bridged phthalocyanine dimers, e.g., [tBu₄PcIn]₂O, tBu₄PcIn O GaPctBu₄ and [tBu₄PcGa]₂O. We demonstrate that the long lived state of the dynamics is the triplet state and the behavior of the degenerate pump-probe was determined by exciton-exciton annihilation (E-EA), nonradiative recombination (NR) and intersystem crossing (ISC) processes. The E-EA process is via the long-range dipole-dipole interaction between excitons or motion-limited diffuse other than exciton hopping migrations. The dimers shows much efficient E-EA and the indium-contained samples have larger ISC rate than the others.
