| Abstract: | The synthesis of series of 4,4′-dialkyl-2,2′-bithiazole oligomers, (ABTz)1,2, and their 5-carboxylic acid derivatives is described. The Langmuir–Blodgett film-forming behavior of the several of the bithiazole dimer carboxylic acids was explored. The compounds form LB films with areas per molecule increasing from 32 to 40 Å2 as the length of the alkyl side chain increases from ethyl to hexyl. |
