A series of supramolecular polymers and networks with variable liquid crystalline characteristics have been created. These species are formed through the benzoic acid/pyridine hydrogen bonding of a flexible bis-acid and a mixture of a rigid bis-pyridyl and non-mesogenic tris- and bis-pyridyl molecules. The tris networ…

High quality FeSe thin films with different ratios of Fe to Se have been grown on GaAs and Si substrates by changing the flow rate of Fe(CO) 5 in a low-pressure metal–organic chemical vapor deposition (MOCVD) system. For both substrates, the films grown at a low flow rate of Fe(CO) 5 are non-ferromagnetic and exhibit…

Abstract A simple chemoenzymatic strategy for the synthesis of colored and fluorescent poly(ε‐caprolactone) esters has been developed. The procedure involves first the reaction of a functionalized primary amine with ε‐caprolactone, to give an amide with a terminal primary hydroxy group, followed by an enzymatic ring‐o…

Dual frequency liquid crystal (DFLC) compounds with high birefringence and ultra-low crossover frequency have been developed. The long conjugated rigid core structure gives these compounds a high birefringence (0.3–0.4) and ultra-low Debye relaxation frequency. Using these compounds we have formulated a new DFLC mixtu…

Uniform drying causes a quasi-two-dimensional cellular crack pattern in a thin layer of paste. In our previous research, we found that such cracks are created in a capillary state, and that the growth speed is determined by the rate of increase in tension in the layer, rather than by the magnitude of the tension itsel…
