discotic mesogen

https://doi.org/10.1351/goldbook.13812

Mesogen composed of relatively flat, disc- or sheet-shaped molecules [6].

Note: The adjective "discotic" is also employed to describe the nematic mesophases formed by discotic mesogens. The mesophases formed by a columnar stacking of disc-like molecules are described as columnar mesophases.
Examples: Discotic mesogens include (a) hexakis(acyloxy)benzenes, (b) hexakis(acyloxy)- and hexaalkoxy-triphenylenes, and (c) 10,15-dihydro-5H-diindeno [1,2 a1′,2′-c]fluorene derivatives.
