From Table 2, it is confirmed that compounds according to the Examples have remarkably small ΔEST values, maintain similar OSCs, and show larger OSCs, as compared with compounds DABNA-1 and 1-2694.

The HOMO and LUMO orbitals of Compounds 5, 17, 49, 51, and 55 and compounds DABNA-1 and 1-2694 were analyzed and compared through simulation, and results thereof are shown in Table 3 and FIG. 5.
