Anarchy in the solid state: structural dependence on glass-forming ability in triazine-based molecular glasses
摘要:
We have recently shown that molecular glasses, small molecules capable of readily forming glassy solids as opposed to crystals, can be designed by exploiting molecular association through strong and directional intermolecular interactions, as exemplified by several members of the bis(mexylantino)triazine family. Herein, 43 new bis(mexylamino)triazine derivatives were synthesized, 31 of which have been found to spontaneously form glassy phases and did not crystallize upon heating.

A liquid crystal polymer represented by the following formula (I):
wherein D represents a n-valence connecting group; n represents an integer of 3 to 20; L
1
represents a single bond or a bivalent connecting group; P represents a polymer having at least one ester bond and/or amide bond and having a weight-average molecular weight of 1,000 or more; m represents an integer that satisfies the relation of n≧m; R represents a hydrogen atom or a substituent; when a plurality of L
1
, a plurality of P, or a plurality of R are present in a molecule, they may be the same or different from each other; and P and P, or P and R may bond together.
