Brominated pentannulated dihydrotetraazapentacenes were prepared by gold- or palladium-catalyzed 5-endo-dig cyclization of TIPS-ethynylated dihydrotetraazaacenes (TIPS = triisopropylsilyl). Post-functionalization was demonstrated by Sonogashira alkynylation and Rosenmund-von Braun cyanation. Calculations predict these species to act as n-type semiconductors, which was verified for two derivates through characterization in organic field-effect transistors.
通过金或钯催化的TIPS-乙炔基化二氢四氮杂并五苯（TIPS = 三异丙基甲硅烷基）的5-内型-亲核环化反应制备了溴化五元二氢四氮杂并五苯。通过Sonogashira炔基化反应和Rosenmund-von Braun氰化反应证明了后官能化。计算预测这些物质可作为n型半导体，通过在有机场效应晶体管中的表征对两种衍生物进行了验证。
