The design and fabrication of nonlinear absorption molecule-embedding solid-state optical power limiting materials are significant but challenging. In the present study, we first report on the synthesis and optical properties of two poly(arylene ether)s incorporating platinum acetylide in the backbones, as well as the fabrication of solid-state optical power limiting materials based on the prepared polymers. The concentrations of platinum acetylide chromophores in the polymer chains were examined to be 19 wt% and 26 wt%, which are the highest levels for non-metal polyyne polymers. Poly(arylene ether)s with platinum acetylide exhibited good mechanical strength, thermal stability, and high glass transition temperature. Investigation of their photophysical behavior revealed that at a high linear transmittance, the polymers showed longer triplet state lifetimes and larger nonlinear absorption coefficients than the corresponding platinum acetylide monomers as a result of the shielding effect. Solid-state monoliths based on platinum acetylide-incorporating poly(arylene ether)s exhibited excellent reverse saturable absorption and optical limiting performance at 532 nm, compared to the optically opaque platinum acetylide chromophore doped polymer monoliths that are formed by severe aggregation.

基于乙炔铂（ii）配合物的聚（亚芳基醚）：合成以及光物理和非线性吸收特性†

嵌入非线性吸收分子的固态光功率限制材料的设计和制造是重要的，但具有挑战性。在本研究中，我们首先报道了在主链中掺入乙炔铂的两种聚（亚芳基醚）的合成和光学性质，以及基于所制备的聚合物的固态光功率限制材料的制造。聚合物链中乙炔化铂生色团的浓度经检测为19 wt％和26 wt％，这是非金属聚炔聚合物的最高含量。具有乙炔铂的聚（亚芳基醚）具有良好的机械强度，热稳定性和较高的玻璃化转变温度。对它们的光物理行为的研究表明，在高线性透射率下，由于屏蔽作用，该聚合物与相应的乙炔化铂单体相比，显示出更长的三重态寿命和更大的非线性吸收系数。与掺有光学不透明的掺有乙炔铂的生色团的聚合物整料相比，基于掺有乙炔铂的聚（亚芳基醚）的固态整料在532 nm处表现出优异的反向饱和吸收和光学限制性能。
