| Outline of Final Research Achievements |
This research showed the validity of the new concept for controlling the solid-state ESIPT luminescence property based on the polymorphism of supramolecular assembly without changing chemical structure of compounds ("fine" control mechanism) by means of X-ray crystallographic analysis and quantum chemical calculation, in addition to the conventional synthetic modification of the electronic state of compounds ("coarse" control mechanism). Combination of the above two controlling mechanisms were confirmed to be useful for tuning the luminescence wavelength gradually and widely, which surely presented considerable potential leading to a valuable designing concept for developing novel organic luminescent materials.
