Non-linear disulphide-centred S-shaped oligomers with inner and outer spacers connected by aromatic azo moieties

The synthesis and enhanced thermal-optical properties of nanocomposites fabricated from gold nanoclusters ([Au25(SC12H25)18]TOA) and non-linear S-shaped liquid crystalline materials

“…2(b), the peak occurring at 356-365 nm could be due to the n-p* electronic transition. 39 In Fig. 2(c), two peaks were observed at 360-377 and 550-650 nm.…”

The effects of alkylthio chains on the properties of symmetric liquid crystal dimers

“…Liquid crystal dimers may be considered to have an inversion of the conventional low molar mass liquid crystal structure by having a highly flexible core. 43 Sulfur atoms have been incorporated into the spacer of liquid crystal dimers previously [44][45][46] and used as the link between the spacer and the mesogenic units. [47][48][49][50][51][52][53][54][55][56] The role of the terminal chains in liquid crystal dimers is to exert control, at least to some extent, over the melting point and phase behaviour.…”
