A novel type of dibenzothiophene [b]-fused core-expanded azaBODIPYs were obtained through an efficient post-functionalization of tetrabrominated azadipyrromethenes, using CuI-catalyzed cyclization, followed by BF2 complexation. These dyes show nearly planar skeletons, strong NIR absorption with maximum peaks up to 733 nm, and remarkable low-lying LUMO level of -4.15 eV. The field-effect transistor based on 1b exhibits bipolar transport properties, with the highest electron and hole mobilities up to 0.012 and 0.046 cm2 V-1 s-1, respectively.

双苯并噻吩融合的叠氮吡咯烷酮的BF2配合物的合成和半导体特性。

一种新型的二苯并噻吩[b]融合的核心扩展的azaBODIPYs是通过使用CuI催化的环化作用,然后进行BF2络合,对四溴化的氮杂二吡咯烷酮进行有效的后官能化而获得的。这些染料显示出几乎是平面的骨架,具有很强的NIR吸收能力,最大峰值可达733 nm,并且具有低至4.15 eV的低LUMO能级。基于1b的场效应晶体管具有双极传输特性,其最高电子迁移率和空穴迁移率分别高达0.012和0.046 cm2 V-1 s-1。
