找到了π电子给体分子BEDT-TSeF的可靠合成方法。 在我们的合成中的关键步骤是反应性的1，4-亚乙基二硫代-5，6-二硒醇二阴离子的分离作为其钛茂络合物，该络合物易于与三光气反应生成4，5-亚乙基二硫代-1，3-二硒醇-2-酮。 BEDT-TSeF晶体与BEDT-TTF晶体是同构的。 利用电化学结晶技术，在不同的抗衡阴离子存在下，得到了多种高导电性的阳离子自由基盐（特别是θ型和κ型盐）。
We have found the reliable synthetic method of the pi-electron donor molecule BEDT-TSeF. The key step in our synthesis is the isolation of the reactive 1,4-ethylenedithio-5,6-diselenolate dianion as its titanocene complex which easily reacts with triphosgene to give 4,5-ethylenedithio-1,3-diselenol-2-one. The crystal of BEDT-TSeF is isostructural with that of BEDT-TTF. A variety of highly conductive cation radical salts (especially, theta and kappa-type salts) were obtained by electrochemical crystallization with various counter anions.
