Mono- and multilayers of molecular spoked carbazole wheels on graphite
نویسندگان
چکیده
Self-assembled monolayers of a molecular spoked wheel (a shape-persistent macrocycle with an intraannular spoke/hub system) and its synthetic precursor are investigated by scanning tunneling microscopy (STM) at the liquid/solid interface of 1-octanoic acid and highly oriented pyrolytic graphite. The submolecularly resolved STM images reveal that the molecules indeed behave as more or less rigid objects of certain sizes and shapes - depending on their chemical structures. In addition, the images provide insight into the multilayer growth of the molecular spoked wheels (MSWs), where the first adlayer acts as a template for the commensurate adsorption of molecules in the second layer.

The synthesis of hexakis-terpyridine and an expedient approach to its dynamic hexakis-heteroleptic complexes are elaborated, the latter being readily accessible precursors for the construction of technomimetic molecular spoked wheels.
متن کاملComparison of wheelchair wheels in terms of vibration and spasticity in people with spinal cord injury.
A wheelchair undergoes vibrations while traveling over obstacles and uneven surfaces, resulting in whole body vibration of the person sitting in the wheelchair. According to clinicians, people with spinal cord injury (SCI) report that vibration evokes spasticity. The relatively new Spinergy wheelchair wheels (Spinergy, Inc; San Diego, California) are claimed to absorb more road shock then conve...

This thesis reports on the investigation of self-assembled monoand multilayers from nanographene derivatives via scanning tunneling microscopy (STM) at solid-liquid interfaces. Because of the unique electronic properties associated with their π-bonded topology, nanographenes are promising building blocks for molecular and organic electronics, which provide the possibility of tunability together...

Interfaces provide the structural basis for function as, for example, encountered in nature in the membrane-embedded photosystem or in technology in solar cells. Synthetic functional multilayers of molecules cooperating in a coupled manner can be fabricated on surfaces through layer-by-layer self-assembly. Ordered arrays of stimulus-responsive rotaxanes undergoing well-controlled axle shuttling...
متن کاملA note on Spoke Count in Aerodynamic Bicycle Wheels
Since the advent of the modern deep section aerodynamic bicycle rim, there have been numerous and often divergent theories about what constitutes an aerodynamic spoke configuration. Theories even arose in the mid 1980’s thinking that higher spoke count wheels would force the air to move around the entire spoked area of the wheel, causing the wheel to behave similar to a disc. This particular th...
