Abstract

Bis-fused tetrathiafulvalenes with mono-and dicarboxylic acids, 2-{5-(1, 3-dithiol-2-ylidene)- [1, 3] dithiolo [4, 5-d][1, 3] dithiol-2-ylidene}-1, 3-dithiole-4-carboxylic acid (1) and 2-{5-(1, 3- dithiol-2-ylidene)-[1, 3] dithiolo [4, 5-d][1, 3] dithiol-2-ylidene}-1, 3-dithiole-4, 5-dicarboxylic acid (2) have been synthesized. The electronic structure of 1 and 2 was examined from their optical absorption spectra and using density-functional calculations.
