| Research Abstract |
Based on the imidazopyrazinone molecular system related to Cypridina bioluminescence, studies were undertaken to elucidate the chemiexcitation mechanism to increase luminescence efficiency and to construct a high-performance chemiluminescence system. The studies on the chemiexcitation process lead to (1) clarify the role of π-conjugated substituents to modulate charge transfer in chemiexcitation and (2) establish the fundamental chemiluminescent property of (trialkoxyphenyl)imidazopyrazinones for investigating the effect of intermediate conformations. (3) The position effect of a π-conjugated substituent on chemiluminescence character of the imidazopyrazinones was also confirmed for designing a high-performance chemiluminescent derivative.
