Thermally tunable selective formation of self-assembled fibers into two orthogonal directions in oriented liquid-crystalline smectic templates

Abstract

Two orthogonal (grid-like) and one directional fibrous structures are selectively formed through anisotropic self-assembly of low-molecular-weight gelators in liquid-crystalline smectic A templates depending on thermally tuned layered structures.

Wet spinning and 3D printing of supramolecular hydrogels in acid-base and dynamic conditions

“…Gelation of LMWG can be triggered by different means (temperature, solvent shift, pH, enzymes 8,26,27 , light 28 , etc.) and subtle changes of these triggers can strongly change the properties of the self-assembled objects and the resulting gels 16,[29][30][31][32][33][34][35][36][37][38] . Molecular hydrogels have been developed for various applications, including biomaterials 11,34,[39][40][41][42][43][44] , drug delivery 10 , 3D printing 45,46 , scaffolds for mineralization 47 , 48 etc.…”

Cooperatively assembled liquid crystals enable temperature-controlled Förster resonance energy transfer

“…Using FRET, ratiometric temperature sensing has been achieved using semiconducting polymer dots. 33 Conversely, stimuli-responsive liquid crystals [34][35][36] without FRET also promise interesting interactions among light, mechanical force, and temperature.…”

Mesogenic discrete metallofoldamer for columnar liquid crystal

“…The absorbance maximum was observed when the polariser was set perpendicular to the sheared direction. 17 The absorbance band of the O–CC–C bond exhibited a large dichroic ratio (A ‖ /A ⊥ ) of 3.1. These results clearly show that the β-diketonate moiety of 1 S,S -Ni is oriented perpendicular to the sheared direction.…”
