Diacetylene films

Diacetylene Films and Optical Guided Vave Structures... 

A membrane for a DNA-probe of a microelectronic biosensor based on Langmuir-Blodgett (LB) diacetylene film with covalently bonded DNA has been developed [86]. Diacetylene films formed on the surface of oxidized silicon by the LB method were used for covalent immobilization of DNA molecules, using the standard W./V -dicyclohexylcarbodiimide...

Besides single crystals, disubstituted diacetylene polymer thin films can be obtained for waveguide applications by evaporation, solidification, or deposition of the diacetylene monomers by the Langmuir-Blodgett approach, which allows film thicknesses to be controlled at the molecular level. These diacetylene films can be patterned using selective polymerization techniques such as developed for...

The above findings are directly relevant to the study of diacetylene films. Since homoepitaxy does not occur in the presence of multivalent metal ions, the emphasis should be shifted to materials which can be deposited on a pure water subphase - some have already been demonstrated. It is predicted that these materials will also display heteroepitaxy with fatty acid monolayers.
