“…It has previously been shown that attaching alkyl tails on a chemical compound often stabilises the compound liquid state. [21,23] Moreover, liquid mono-anthracene compounds produced by this method have also been previously reported. [23] Here the point is that one of the causes for the stabilisation of the molecule in the liquid state is the bent shape of the rigid terminal unit.…”

Reworkable adhesion of glass plates was demonstrated using colourless adhesives. This was achieved using anthracene-terminated liquid compounds with hexamer structures (2500 g mol −1) as adhesives, which are photo-crosslinkable and thermo-degradable materials. It was found that the substitution position at the anthracene was important to obtain liquid-phase compounds at room temperature. However, although the compounds were liquid, they were too viscous to be used as adhesive. Therefore, they were mixed with 25 wt.% of dibutyl phthalate to increase fluidity. The liquid mixture could then be applied to the glass substrates without further modification, and was curable via photodimerisation of anthracene moieties to tightly attach the glass substrates together. The cured material was stable up to 120°C, but it returned to the original liquid state at room temperature after heating at 180°C, resulting in the detachment of the substrates without applying any strong force. The cycles of the curing and liquefying processes was reproducible for at least five consecutive times.
