“Most MCL materials generate two colors by switching between a stable state and one metastable state. To realize multi-color MCL, more metastable states are necessary,” explain Professors Youhei Takeda and Satoshi Minakata at the Department of Applied Chemistry, Graduate School of Engineering of Osaka University.
“By making the use of a promising and unique acceptor, dibenzophenazine (DBPHZ), which we previously developed, we made a PTZ-DBPHZ-PTZ triad,” said Takeda. “In this structure, the PTZ moiety could take two distinct conformers, which therefore in principle creates in total four metastable states as a whole molecule.”
Takeda says that, “Our molecule could become a basis for efficient light-emitting devices and pressure- and temperature-responsive sensors in the future.”
