Unidirectional Rotation in Catenanes
In this work, two different catenane based molecular motors were reviewed. These motor molecules consist of two interlocked rings, one of which has binding sites for the other ring. The smaller ring without the binding sites can rotate over the other macrocycle when the affinities of the binding sites are changed. If the rotation is unidirectional the molecule could in principle perform work. I...
متن کاملQuantum unidirectional rotation directly imaged with molecules
A gas-phase molecular ensemble coherently excited to have an oriented rotational angular momentum has recently emerged as an appropriate microscopic system to illustrate quantum mechanical behavior directly linked to classical rotational motion, which has a definite direction. To realize an intuitive visualization of such a unidirectional molecular rotation, we report high-resolution direct ima...
متن کاملKinetic analysis of the rotation rate of light-driven unidirectional molecular motors.
The combination of a photochemical and a thermal equilibrium in overcrowded alkenes, which is the basis for unidirectional rotation of light-driven molecular rotary motors, is analysed in relation to the actual average rotation rates of such structures. Experimental parameters such as temperature, concentration and irradiation intensity could be related directly to the effective rates of rotati...

We aimed to determine the frequency and basis for inpatient consultation with the paediatric cardiology service in a tertiary teaching hospital. Information regarding new patient refer...
متن کاملUnidirectional rotary motion in achiral molecular motors.
Control of the direction of motion is an essential feature of biological rotary motors and results from the intrinsic chirality of the amino acids from which the motors are made. In synthetic autonomous light-driven rotary motors, point chirality is transferred to helical chirality, and this governs their unidirectional rotation. However, achieving directional rotary motion in an achiral molecu...
