The self-assembly of molecules into complex superstructures underpins the functionality many biological processes and physical materials. Many such structures stem from amphiphilic monomer units, with attractions repulsions between their ends determining structure state assembled system under equilibrium, which affect its function. photophysical electronic properties fullerene (C60) have been e...

Plaque disruption with superimposed thrombosis is considered to be responsible for precipitating acute coronary syndrome. We identified sn-1-alkyl- and sn-1-acyl-type glycerophosphocholine (GroPCho) core aldehydes from human atheromas and demonstrated their activities on platelets and arteries. The naturally occurring core aldehydes were identified and quantified in relation to synthetic standa...

Cellular damage and inflammatory processes cause activation of phospholipase A in plasma membranes resulting in the production of various lysophospholipids. Treatment of mice with L-alpha-lysophosphatidylcholine, a decomposition product of phosphatidylcholine, greatly stimulates mouse peritoneal macrophages to ingest target cells via the Fc receptors. Similarly, treatment of mice with L-alpha-l...

Novel two-dimensional C3 symmetric (tripod) structures are fabricated from isobutenyl compounds possessing long alkyl chains. Alteration from tripod to wavy structures is accomplished by odd-even effect, and tandem Claisen rearrangement allows the transformation to the linear structures.

The title compound, C(20)H(26)O(4), crystallizes such that the alkyl chain adopts an all-anti conformation. The crystal packing displays edge-to-face arene-arene inter-actions with a dihedral angle of 87°. The complete molecule is generated by inversion symmetry.

High pressure limits of thermal rate constants of intramolecular hydrogen migrations, particularly 1,3 to 1,6 H-shift in propyl, butyl, pentyl and hexyl radicals, respectively, were calculated using the canonical variational transition state theory (CVT) with a multi-dimensional small-curvature tunneling (SCT) correction over the temperature range of 300-3000 K. The CCSD(T)/cc-pVDZ//BH&HLYP/cc-...

A series of isobutenyl compounds possessing various alkyl chain lengths (C(n)-1) with a carbon number of n = 14-21 were synthesized and their two-dimensional (2D) structures were systematically studied using scanning tunnelling microscopy (STM) at a highly oriented pyrolytic graphite (HOPG)/solvent interface. Two kinds of solvent, such as 1-phenyloctane (PO) and 1-phenylnonane (PN), were select...
