Abstract

The hybrid co-networks (PTA-Fe) of poly(thioctic acid) (PTA) coordinated with Fe³⁺ having PTA polymers with the number-average molecular weight (M_n) of 1–60 kg mol⁻¹ and molar Fe³⁺ content (C_Fe) of 0%–31% have been successfully in situ synthesized. The PTA-Fe film shows high transmittance of 97% with 6.9% ≤ C_Fe ≤ 16.1% and M_n ≥ 12.5 kg mol⁻¹. The PTA-Fe film reveals self-focusing phenomenon especially under 808 nm irradiation, due to the nonlinear refraction caused by the polarized charge transfer complex (CTC) in hybrids excited photons. Meanwhile, the refractive index at 589 nm (n_D) of PTA-Fe hybrid increases from 1.54 to 1.68 with incremental C_Fe for the disulfides and CTC structures. The Abbe number (ν_D) of PTA-Fe hybrids slightly decreases (47–45) due to their self-focusing behavior. The PTA-Fe materials show adjustable photothermal conversion under 808 nm irradiation by mediating C_Fe or NIR intensity (I₈₀₈). The photothermal conversion efficiency (PCE) of PTA-Fe hybrid can reach 98% even at low I₈₀₈ of 50 mW cm⁻², for the PTA-Fe hybrid with self-focusing character can converge the light into a point inside the materials. The multifunctional PTA-Fe hybrid co-networks with high performance in optical transparency, focusing, and photothermal conversion would have potential applications in advanced optical materials.

Fe3+配位聚硫辛酸杂化共网络的光学性能：光学聚焦与光热转换

本文成功地原位合成了聚硫辛酸（PTA）与Fe3+配位的杂化共网络（PTA- fe），具有数平均分子量（Mn）为1 ~ 60kg mol−1，Fe3+摩尔含量（CFe）为0% ~ 31%的PTA聚合物。PTA-Fe薄膜具有97%的高透光率，其中CFe≤6.9%,Mn≥12.5 kg mol−1。PTA-Fe薄膜在808 nm辐照下表现出自聚焦现象，这是由于杂化激发光子的极化电荷转移复合物（CTC）引起的非线性折射所致。同时，二硫化物和CTC结构的PTA-Fe杂化物在589 nm处的折射率（nD）随CFe的增加从1.54增加到1.68。由于PTA-Fe杂化体的自聚焦行为，其阿贝数（νD）略有降低（47 ~ 45）。PTA-Fe材料在808 nm的CFe或NIR照射下表现出可调节的光热转换（I808）。由于具有自聚焦特性的PTA-Fe杂化材料可以将光汇聚到材料内部的一个点上，因此即使在50mw cm−2的低I808下，PCE也能达到98%。具有光学透明性、聚焦性能和光热转换性能的多功能PTA-Fe混合共网络在先进光学材料中具有潜在的应用前景。
