Abstract:
We constructed regular cubes using chiral copper clusters and fluorescent dyes with tunable fluorescence and circularly polarized luminescence (CPL). Its concentration-dependent fluorescence switching and CPL activity are governed by radiative energy transfer and chirality transfer. Upon tetrahydrofuran (THF) addition, the assembly disassembles into lamellar structures, restoring the original blue emission and CPL signal.
