Both compounds display photoluminescences in the visible region under visible-light excitations, and their thermochromism effects are observed. But their photoluminescence and thermochromic behaviors differ greatly with the presence or absence of hydrogen bonds. Moreover, their absorption spectra have also been discussed.
