Synthesis and characterisation of novel electronic materials.

-4Scm-1 whereas the hexamethyl was insulating. This was proposed to be due to differing stacking characteristics.The properties of the ternary salts were proved to be intrinsic and not solvent induced.The failure of the amphiphilic dipyrrylmethene to complex with TCNQ was proposed to be due to steric hindorance which encumbers the close approach of the TCNQ. The Langmuir film of the dipyrrylmethene was shown to undergo re-orientation on the subphase. The L-B film of a picolinium TCNQ charge transfer salt was shown not to under go a molecular re-orientation due to the increase in the area of the hydrophobic aliphatic chains.
