摘要

利用 Horner-Wadsworth-Emmons 烯化反应，从合适的二酮前体合成了两种含有二茚并熔茱萸烯间隔物的广义四硫杂戊烯（TTF）。根据溶解变色行为和前沿轨道计算推断，这两种化合物都是具有最长吸收波长的强发色团，并表现出一定程度的电荷转移特性。在循环伏安条件下，这些化合物经历了两次可逆的单电子氧化和准可逆的第三次氧化。单阳离子和双阳离子具有特征性的近红外吸收，并且都具有 EPR 活性。具有潜在类二极体特征的二阳离子在批量生成时发生了反应。

Diindeno-Fused Corannulene-Extended Tetrathiafulvalenes

Two regioisomeric extended tetrathiafulvalenes (TTFs) incorporating diindeno-fused corannulene spacers were synthesized from suitable dione precursors using Horner-Wadsworth-Emmons olefination reactions. Both compounds are strong chromophores with a longest-wavelength absorption that exhibited some degree of charge-transfer character as inferred from solvatochromic behaviors and frontier orbital calculations. The compounds underwent two reversible one-electron oxidations and a quasi-reversible third oxidation during cyclic voltammetry conditions. The mono- and dications had characteristic NIR absorptions and both were EPR active. The dications with potential diradicaloid characters underwent reactions when generated in bulk.
