The absorption band at 474 nm (ε = 1.2×10 4 M -1 cm -1 ) is associated with the characteristic SRCT state and is both red-shifted and weaker compared to the SRCT band of DiKTa (labs = 435 nm with ε = 2.1×10 4 M -1 cm -1 ), likely implicating that this state in DDiKTa-A contains an admixture of SRCT and LRCT character. The steady-state photoluminescence (PL) spectrum in toluene of DDiKTa-A is broad, having a peak at lPL of 551 nm and a FWHM of 76 nm. This emission is significantly red-shifted and broader compared to that of DDiKTa (lPL = 470 nm, FWHM = 47 nm), of DiKTa (lPL = 453 nm, FWHM = 27 nm), and of DiDOBNA-N (lPL = 426 nm, FWHM = 43 nm). Distinct from that observed for these three compounds, there is a more significant positive solvatochromism (Figure ) that is consistent with of an emissive excited state that possesses mixed SRCT and LRCT character.
