a UV–visible spectroscopy in methylene chloride (1.0\(\times {10}^{-5}\) M) and photoluminescence spectroscopy in 5 wt% doped PMMA of PtON-TBBI, PtON-tb-DTB, and PtON-tb-TTB. b Shifted spectra of PtON-tb-DTB and PtON-tb-TTB to that of PtON-TBBI for comparison of the vibrational bands. c Measurements of time-resolved photoluminescence (TRPL) spectra by using 5 wt% doped on the PMMA matrix.
