The Q absorption band of the excited triplet phthalocyanine dimer

Summary:The excited triplet state absorption spectrum of a self-assembled dimer of tri- tert-butylpyridinotribenzotetraazaporphinatozinc, (ZnPcPy) 2, exhibits two sharp absorption bands in the Q band region, which is the first Q band observation of the excited triplet phthalocyanine dimer. The lowest excited triplet (T 1) state of tri- tert-butylpyridinotribenzotetraazaporphinatozinc (ZnPcPy) has been investigated using transient absorption and phosphorescence measurements. The excited-state absorption spectrum of the self-assembled dimer ((ZnPcPy) 2) exhibits two sharp absorption bands (658 and 694 nm) in the Q band region, in addition to triplet-triplet absorption at 500 nm. This is the first observation of the Q band of the T 1 phthalocyanine dimer.
