An exploration of the photophysical properties of two lophine derivatives with electron-donating groups in the 2-position began with the preparation of compounds 1 and 2 via one-pot reactions in good yields, 83% and 74%, respectively. The absorption spectra of 1 and 2 had bands at approximately 300 nm (ε ≈ 25,000–34,000 M−1 cm−1), while that of 2 had an additional band at 348 nm (ε = 35,600 M−1 cm...
