(a) Excitation anisotropy spectra of 1 in pTHF (1), DMSO (2), cyclohexane (3), toluene (4), THF (5), DCM (6), hexane (7), and ACN (8). (b) Dependences r/r_hex =f(λ_ex) for 1 in cyclohexane (1), THF (2), DCM (3), and ACN (4). (c) Dependence $1/r({\lambda }_{\mathit{\text{abs}}}^{\text{max}})=f(1/\eta )$ for 1 in organic media. (d) Dependences r/r_hex =f(λ_ex) for 1 in DMSO (1), toluene (2), and pTHF (3). Normalized one-photon absorption spectrum of 1 in hexane: (a) curve 9; (b) 5, and (d) 4.
