  Photo- and Electroluminescence from Organoplatinum(II) Complexes Bearing Oligofluorene-Based Cyclometalated Ligands

  摘要：

  To develop phosphorescent materials for organic light-emitting diodes (OLEDs), novel organoplatinum(II) complexes bearing oligofluorene-based cyclometalated ligands were synthesized. These materials exhibited intense reddish orange photoluminescence (PL) and thus were applied as emitting dopants to OLEDs. The fabricated OLEDs showed electroluminescence identical to PL of the corresponding dopants. A non-doped device was also successfully fabricated using the developed complex as an emitting layer.

  通过顺序点击耦合的药物传递和细胞成像合成热敏共轭三嵌段共聚物。

  摘要：

  出色的发光片段和生物相关信号响应部分的完美结合可以产生先进的聚合物输送系统，同时具有相对于癌症治疗学而言有利的诊断和治疗功能。尽管已经广泛开发了基于荧光聚芴（PF）或热响应性聚（N-异丙基丙烯酰胺）（PNIPAAm）的聚合物输送系统，但由PF嵌段，PNIPAAm序列和亲水部分组成的三元聚合物配方的制备仍然很少由于可能难以整合用于聚合物合成的不同合成策略的困难，因此进行了探索。为此，在本文中我们报道了基于PF和PNIPAAm的两亲三嵌段共聚物PF 11的设计和可控合成。- b -PNIPAAm 120 - b -聚（低聚（乙二醇）单甲醚甲基丙烯酸酯）17（PF 11 - b -PNIPAAm 120 - b -POEGMA 17），通过铃木耦合生成的PF与原子转移自由基聚合（ATRP）生成的PNIPAAm和POEGMA之间的顺序点击耦合策略，具有明确定义的结构。所制备的三嵌段共聚物可以自组装

  Controlled Pd(0)/t-Bu3P-catalyzed Suzuki cross-coupling polymerizations of AB-type monomers via the chain-growth mechanism with an ArPd(t-Bu3P)I complex as the initiator are described. ArPd(t-Bu3P)I complexes, either prepurified or generated in situ from Pd-2(dba)(3)/t-Bu3P/ArI (dba = dibenzylideneacetone) without separation/purification, were found to be efficient initiators in general for the controlled Suzuki cross-coupling polymerization, with narrow polydispersity indexes (PDIs) of 1.13-1.35 being observed. The Pd-2(dba)(3)/t-Bu3P/p-BrC6H4I combination was identified as a highly robust initiator system, with PDIs of <= 1.20 in general and as low as 1.13 being obtained. Higher number-average molecular weights (M-n) were achieved without a significant increase in the PDI (from 1.14 for a polymer with a M-n = 9500 to 1.20 for a polymer with M-n = 31 400) by using a smaller amount of the Pd-2(dba)(3)/t-Bu3P/p-BrC6H4I initiator in the polymerization.
