The ultrafast transient dynamics of a free-base tetraphenylporphyrin (H 2 TPP) surface-mounted metal organic framework (SURMOF) is spectroscopically characterized and compared with that of H 2 TPP in ethanol solution. A dramatic increase of the quantum yield of the Soret band fluorescence (S 2 → S 0 ) is observed in the H 2 TPP−SURMOF, which is accompanied by an increase of the S 2 fluorescence lifetime and a broadening of the fluorescence spectra. In contrast, the Q band (S 1 ) fluorescence is strongly quenched in the H 2 TTP SURMOF compared with the fluorescence of H 2 TTP in ethanol solution. The observed transient absorption kinetics supports the fluorescence data. The enhanced fluorescence in the SURMOF compared with H 2 TPP in solution is attributed to the combination of two factors: the alignment of the vibrational energy levels of the dominant Franck−Condon active mode of the Soret and Q bands and the weaker coupling of these modes to the environment.

“…7 shows the UV-vis absorption spectra of (a) HST-TPP and (b) unintercalated TPP. In the spectra, Soret band at 424 nm and Q bands at 520, 556, 595.5, 653 nm can be clearly observed, which correspond to the absorption bands for tetraphenylporphyrin [16] (Soret band at 414 nm and Q bands at 512, 545, 589, 648 nm). HST-TPP hybrid holds the same wavelengths of absorption peaks relative to the unintercalated TPP, but the absorption becomes weaker.…”

Excited state dynamics, particularly intersystem crossing, of a set of meso-substituted porphyrins bearing different electron-donor and acceptor groups was studied by pulse train fluorescence technique. Triplet quantum yield was found to be critically dependent on the nature of meso-substituents in the porphyrin system. Porphyrins with meso methoxyphenyl groups were found to show high triplet Studying the intersystem crossing rate and triplet quantum yield of meso-substituted porphyrins by means of pulse train fluorescence technique.
