The chemical structures of the Pt-TBT monomer and its deuterated counterpart.
The FTIR and Raman spectra of non-deuterated (H) and deuterated (D) Pt-monomer. The assignments of the peaks are discussed in detail in Table II.
The refractive index (solid lines) and absorption spectra (dashed lines) of the deuterated Pt-containing monomer. The non-deuterated analogues have very similar refractive index dispersions.
Thin film phosphorescence spectra of the deuterated and non-deuterated compounds at 10 K (dotted lines) and the Franck-Condon fit (solid lines).
The decay of the phosphorescence measured at 10-5 M (per repeat unit) in MeTHF at 80 K. The laser pulse occurs at 0 μs.
Synthetic and spectroscopic data for the Pt-containing non-deuterated (Pt-TBT H) and deuterated (Pt-TBT D) monomer.
Approximate wavenumbers and energies of Raman (0–7) and FTIR (a)–(c) peaks as shown in Figure 2 and their assignments.
The phonon energies (ℏω i ) of the different vibronic modes as determined from Figure 2 and the Huang-Rhys parameters S i calculated from the phosphorescence spectra (Figure 4). The relaxation energy associated with each mode E rel, i = S i ℏω i is also shown along with the total relaxation energies of the individual materials .
