high fluorescence quantum yield, even in the solid state (~0.5), which is advantageous
for photonics applications.
In this chapter, the fluorescence properties of BF 2 DBM in PMMA films and
solution during evaporative crystallization were investigated to reveal the two-step
nucleation model.
2.3.1 Fluorescence Visualization of Crystallization
of Dibenzoylmethanatoboron Difluoride Complex
We have investigated the fluorescence properties of 4,4
-di-tertbutyldibenzoylmethanatoboron difluoride (BF 2 DBMb, Fig. 2.4a) in PMMA
films and solution during evaporative crystallization to reveal the two-step nucleation model [19]. BF 2 DBMb has a mechanofluorochromic property, [11, 20] which
originates from the different emission properties between the amorphous state and
