Abstract

We have studied the evaporative crystallization of dibenzoylmethanato boron difluoride complex (BF2DBM) using the quartz crystal microbalance (QCM) technique and based on fluorescence changes. The optical and mechanical properties of the liquid-like cluster state were observed during the evaporative crystallization process. This state most probably exists as a solvent-containing amorphous phase with optically isotropic state, based on the viscoelastic properties and polarized optical images.
