Solvates of a donor–acceptor-type fluorophore exhibited multicolor luminescence that can respond to mechanical stimuli, solvent and acid vapors.
Eight new multicomponent solid forms of IVA were prepared, the crystal structures were determined and evaluated their physicochemical properties.
Multiple hydrogen bonding patterns between pyromellitic diimide tethered carboxylic acid hosts and identical guest molecules were studied.
Six solid forms of arbutin are successfully obtained and four single crystal structures are reported for the first time. Further, the formation mechanism of arbutin solvates is proposed and rationalized.
This work employed variable-temperature THz spectroscopy to analyze the structural evolution of host–guest energetic CL-20/H2O2 and CL-20/H2O solvates, as well as the mechanism of intermolecular interactions using DFT calculation and MD simulation.
