Merging liquid crystalline self-assembly and linear optical properties of merocyanines via tailored donor units

Abstract

Aiming at merocyanine dyes with good linear optical and self-assembly properties, a series of rigid mono-, bi- and tricyclic merocyanines with O- and N-donor units as well as keto or...

New luminescent ordered liquid crystalline molecules with a 3-cyano-2-pyridone core unit

“…Some examples of heterocyclic core in LCs are thiophene, 20 benzothiazole, 21 pyridine, [22][23][24][25][26][27][28][29] 1,3,4thiadiazole, [30][31][32][33][34] and merocyanines. [35][36][37][38][39] Further, the existence of a donor-acceptor (D-A) type structure in the molecule results in good light absorption and/or emission properties of LCs owing to push-pull driven intramolecular charge transport properties. Additionally, in D-A architectured LCs, donor-acceptor interactions primarily stabilize self-assembly via prolonged conjugation.…”
