Synthesis and optical properties of phenylene-containing oligoacenes.
Summary of "Synthesis and optical properties of phenylene-containing oligoacenes."
Synthesis of a new class of fully unsaturated ladder structures, phenylene-containing oligoacenes (POAs), using 3,4-bis(methylene)cyclobutene as a building block for sequential Diels-Alder reactions is described. The geometric effects of strain and energetic cost of antiaromaticity can be observed via the optical and electrochemical properties of the reported compounds. The resulting shape-persistant ladder structures contain neighboring chromophores that are partially electronically isolated from one another while still undergoing a reduction in the band gap of the material.

Medical and Biotech [MESH] Definitions
LIGHT, it's processes and properties, and the characteristics of materials interacting with it.
Products or parts of products used to detect, manipulate, or analyze light, such as LENSES, refractors, mirrors, filters, prisms, and OPTICAL FIBERS.
Tomography, Optical Coherence
An imaging method using LASERS that is used for mapping subsurface structure. When a reflective site in the sample is at the same optical path length (coherence) as the reference mirror, the detector observes interference fringes.
Nanometer range spherical cores of particular semiconductor compounds surrounded by an ultrathin metal shell that is commonly made of gold or silver. This configuration gives the nanoshells highly tunable optical properties. They have potential in biomedicine for diagnosis and therapy.
Lanthanum. The prototypical element in the rare earth family of metals. It has the atomic symbol La, atomic number 57, and atomic weight 138.91. Lanthanide ion is used in experimental biology as a calcium antagonist; lanthanum oxide improves the optical properties of glass.
