Fig. 3. (a) Normalized absorption (black traces) and PL (blue traces) spectra of LC8 in solvents of different polarity (c = 0.02 mM); (b) absorption (black trace) and PL (blue trace) spectra of a spin-coated film of neat LC8 in comparison with solution-state spectra in toluene (dashed traces). λexc = 350 nm, MCH = methylcyclohexane, PhMe = toluene, THF = tetrahydrofurane, DCM = dichloromethane, PrCN = butyronitrile, SRCT = short-range charge transfer, LRCT = long-range charge transfer.
