| Research Abstract |
The formation conditions of thin films in the electrochemical polymerization of 6-substituted groups-1,3,5-triazine-2,4-dithiol mono sodium salts (RTD) on metals and the structure of thin films were investigated. From the relation between RTD concentration and current density, amorphous organic thin films are formed in the conditions as a rate-determination step is a diffusion process and crystalline films are done in the conditions as a rate-determination step is a one-electron transfer process. Morphology structure of the organic thin films depends upon the chemical structure of substituted groups in RTD. Amorphous organic thin films are formed in the substituted groups of short alkyl chains, and crystalline films in the groups of long alkyl chains. Furthermore, amorphous films are formed when alkyl chains is one, and crystalline films when alkyl chains two. The number of layer can be calculated from current efficiency and polymerization time. RTD containing unsaturated groups in the substituted groups gave three dimensional organic thin films insoluble in organic solvents. Formation rate in the electrochemical polymerization of dioctylamino-1,3,5-triazine-2,4-dithiols increased according to a linear low, suggesting the rate-determining step to be electron transfer process. This organic film is similar to a Y-type LB film but triazine dithiols containing unsaturated groups in the substituted group give a X-type LB film. This films are effective one for producing condensers and non-linear optical devices. Crystal structure analysis for some RTD indicate that polymer films turn on an electric current over a certain potential as be separated in the parts of electron donor and acceptor. The properties will be developed as electric devices such as organic semiconductors, condensers and resistors.
