Photophysical measurements (Table ) in toluene solution (Figure ) provide a platform to accurately compare pertinent rates, as the data can be considered intrinsic, with strictly monoexponential decay for both prompt and delayed fluorescence in the absence of any solid-state phenomena. The absorption (and PL) spectrum of 2 is bathochromically shifted compared with that of 1 due to trans-annular communication, consistent with electrochemical and TD-DFT results. The absorption spectra for 1 and 2 consist of intense transitions below ca. 350 nm, assigned to π-π* excitations, and lower energy broad ICT transitions ≥ 400 nm. Similarly, the PL spectra of 1 and 2 are also ascribed to ICT, being broad and featureless and exhibiting positive solvatochromism (Figure .1).
