“…To enable FCPM, the LC mixture has to be doped with a fluorescent dye. Following the guidance of the original FCPM studies [8,150], we used a dye N,N ′ -bis(2,5-di-tert-butylphenyl)-3,4,9,10-perylenedicarboximide, in FCPM literature called BTBP, but also known as DBPI, with a structure shown in Fig. 5 The dye itself has poor solubility in the CCN mixture.…”

“…1 has been validated using polarization microscopy, 11 electron microscopy, 17 atomic force microscopy, 16 and polarization confocal microscopy. 15 These studies have also established that the size of a toroidal focal conic defect is determined by the length scale of the confining geometry. 9,23 More specifically, the defect size is determined by minimizing the free energy of the defect, accounting for layer curvature, which increases stored elastic energy, and surface anchoring, which reduces surface free energy.…”

“…4,6,[12][13][14] Although it is an imperfect measure of layer structure since it provides only a two-dimensional projection of the structure resulting from integrating the birefringence over the path length, changes in polarization intensity nevertheless indicate the degree to which changes in layer structure have occurred, since any changes in layer alignment will necessarily alter the resulting integrated intensity. Alternate characterization methods such as confocal microscopy, 15 atomic force microscopy, 16 and electron microscopy, 17 have been used to successfully validate static layer structures, but all of these suffer limitations preventing determination of the dynamics of layer structures. The primary limitation is that the structure determination, while more detailed, is quite slow and therefore inappropriate when relatively rapid changes in the structure due to external fields are of interest.…”
