Decay lifetimes (τi), pre-exponential coefficients (αi) and chi-squared (χ2) values obtained from the reconvolution analysis of emission decay curves measured for the DMTPS-Sil-dU(600)-x and DTMPS-dU(600)-x series, detected at the emission wavelength of 600 nm, upon excitation at 375 nm. The PLQY values of each sample are also reported.

Average values and errors are the mean and standard deviation of three independent measurements (λex = 370 nm for dU(600) and 410 nm for DMTPS-Sil-dU(600)-x and DMTPS-dU(600)-x).
