Fig. 2.38 Excitation (dashed lines) and emission (solid lines) spectra of eleven powder forms
(denoted as “P”) and single crystals (denoted as “C”) of 3/solvent, in which 3/solvent corresponds
to a 3/CHCl 3 , b 3/Py, c 3/CH 2 Cl 2 , d 3/CH 2 Br 2 , e 3/DMA, f 3/AcH, g 3/CH 3 CN, h 3/DMF, i 3/SPO,
j 3/racPO, and k 3/acetone. The measurement conditions are summarized in Table 2.5
