A series of ladder-type thienoacenes based on benzo[1,2-b:4,5-b']dithiophene (BDT) have been synthesized and characterized. They were shown to be p-type semiconductors with wide band gaps and able to support multiple stable cationic states. As the conjugation lengthens, these oligomers become more emissive, showing high quantum yields. They were shown to be good two-photon absorbers, exhibiting high two-photon absorption coefficients.
一系列基于苯并[1,2-b:4,5-b']二噻吩（BDT）的梯型噻吩并噻吩类化合物已经被合成并进行了特性研究。这些化合物表现出 p 型半导体的特性，具有较宽的能隙和支持多种稳定阳离子态的能力。随着共轭链的延长，这些齐聚物变得更具发光性，表现出高的量子产率。它们被证明是良好的双光子吸收体，具有高的双光子吸收系数。
