  一系列以芘为电子供体的推挽染料的合成及光学性质。

  摘要：

  已经设计并合成了 15 种包含四环多环芳烃芘的推拉染料。已在 22 种不同极性的溶剂中检测了 15 种染料的光学性质。令人惊讶的是，与经典观察到的 D-π-A 结构推拉染料相反，许多染料都存在负溶剂化显色现象。还检查了染料的光致发光和热性能。进行了理论计算以支持实验结果。

  The actual photonitiators PI can only operate in a restricted part of the visible spectrum; as a consequence, several Pis are usually necessary to harvest all the emitted visible photons. In the present paper, new dyes based on a donor-pi-acceptor structure (1,3-indanedione derivatives) are incorporated into visible light sensitive photoinitiating systems of polymerization. They exhibit an unusual and remarkable broad absorption lying from the blue to the red. When employed in the presence of an iodonium salt (Iod) and optionally N-vinylcarbazole (NVK), these dyes can efficiently initiate the radical photopolymerization of acrylates, the cationic photopolymerization of epoxide and vinylether monomers and the hybrid cure of acrylate/epoxide blends under exposure, e.g, at 405, 457, 473, 532, and 635 nm. They partly behave as organic photocatalysts. These particular light absorption properties and the initiation step mechanisms are investigated in detail.
