Strategies for promoting discotic nematic phases

Abstract

A series of discotic dimers were synthesized in an attempt to obtain nematic discotic liquid crystal phases. Although initial target compounds were nonmesogenic, the incorporation of bulky groups adjacent to...

Useful synthetic artifacts? The impact of ubiquitous linker-adjacent groups on the self-assembly of discotic dimers

“…No Cr-to-LC melting transition was observed for dDBP(hyd,6) by DSC, suggesting that its T m lies below room temperature; this is dramatically reduced compared to the 170 1C melting point of dDBP(hyd,H). Adjacent functional groups appear to destabilize the melting transition much more than the clearing temperature, which we have previously observed for other systems, 33,40 and suggests a general strategy for broadening the Col h temperature range.…”
