a Build-up curves of 1H NMR intensity for o-terphenyl (OTP) doped with pentacene (blue triangles), 6,13-di(thiophen-2-yl)pentacene (DTP) (green squares), and ICBA trans-3a (red circles). Build-up time constants were obtained by fitting the curves (solid lines) with I = A[1−exp( − t/Tb)]. b Build-up curve of 1H NMR intensity of partially deuterated OTP (OTP:[D14]OTP = 10:90 wt%), doped with 0.05 mol% of ICBA trans-3a. Source data are provided as a Source Data file.
