(a) Reflection micrographic images of crystals of complexes 1–5. These images were observed using a confocal laser microscope. (b) Optical micrographs of single crystals of complexes 1–5 under cross polarised light. Crystals were repeatedly heated beyond the phase transition temperatures and cooled.
