  摘要：

  在这项研究中，我们报告了新型角融合氮杂芳烃的合成。为此，可以缩短和优化2（TABEF）的双-二胺的合成。 2与不同类型的1,2-二酮的缩合反应产生了新的氮杂芳烃衍生物，类型为10，11和12。类似地，2与氯化硫酰环化，得到了噻嗪硫醇衍生物13。通过紫外/可见吸收、荧光发射光谱和循环伏安测量，研究了所有新化合物的光学和电化学性质。

  2,3,6,7-Tetraamino-9,9-bis(2-ethylhexyl)fluorene: New Multifunctional Monomer for Soluble Ladder-Conjugated Molecules and Polymers

  摘要：

  2,3,6,7-Tetraamino-9,9-bis(2-ethylhexyl)fluorene (TABEF), as a new multifunctional monomer for ladder-type conjugated molecules and polymers, was efficiently synthesized via a six-step procedure with an overall yield of 30%. Two isomeric ladder compounds based on TABEF building blocks were also synthesized and preliminarily studied.

  FDT and FDT‐Br diradicaloids with stable coexisting close‐shell and open‐shell forms exhibit unconventional self‐doping behavior in solid‐state electronic devices that is temperature (T) tunable and reversible. The doping is strengthened by the increased T, leading to the absence of off‐states (Ioff) in the transistors.

  具有稳定的闭壳和开壳形式并存的FDT和FDT-Br双自由基在温度（T）可调和可逆的固态电子设备中表现出非常规的自掺杂行为。通过增加T来增强掺杂，从而导致晶体管中不存在截止状态（I off）。

  By a controllable and stepwise strategy, a soluble ladder-conjugated perylene derivative BPI-FBI as the only product has been synthesized, which avoids the tough work to isolate regioisomers generated by a conventional one-step condensation method. BPI-FBI exhibits broad absorption spectra covering the whole visible region from 300 to 700 nm because of the large pi-conjugation skeleton and has a low LUMO level inheriting the prototype PDI. In the steady-state space-charge-limited current (SCLC) devices, BPI-FBI exhibits an intrinsic electron mobility of 1.01 x 10(-5) cm(2) V-1 s(-1). With a high two photon absorbing activity in the near-infrared region from 1200 to 1400 nm, BPI-FBI also exhibits good optical limiting performance, which will be useful for sensor or human eye protection and stabilization of light sources for optical communications.
