Novel phtotpolymerisable hole-transport layers based on novel triazatruxenes incorporating six non-conjugated dienes as photo cross-linkable end-groups attached to flexible, aliphatic spacers have been synthesised using simple one-step substitution reactions. Hole-only test devices, fabricated using a combination of solution-deposition, spin-coating and initiator-free photochemical cross-linking of these photopolymerisable triazatruxenes, exhibit almost identical current density voltage profiles before and after cross-linking, and as such, represent a promising new class of hole-transport layer for plastic electronic devices.
基于新型三氮杂并四苯合成了新型光聚合空穴传输层，该三氮杂并四苯包含六个非共轭二烯作为光可交联端基，连接到柔性脂肪族间隔基上，采用简单的一步取代反应即可合成。使用这些可光聚合三氮杂并四苯的溶液沉积、旋涂和无引发剂光化学交联相结合的方法制备的仅空穴测试器件，在交联前后表现出几乎相同的电流密度-电压曲线，因此，代表了一类有前途的用于塑料电子器件的新型空穴传输层。
