study, a new polymer P1 embedded with "H"-type chromophore moieties was designed and synthesized through Suzuki coupling copolymerization, in which the isolation chromophore was introduced to further improve its comprehensive performance. This polymer demonstrated good solubility and film-forming ability. In comparison with normal "H"-shaped NLO polymers only containing one type of chromophore, nearly all
在这项研究中,通过铃木偶联共聚设计并合成了嵌有“ H”型生色团部分的新型聚合物P1,其中引入了分离生色团以进一步提高其综合性能。该聚合物表现出良好的溶解性和成膜能力。与仅包含一种生色团的普通“ H”形NLO聚合物相比,P1的几乎所有性能均得到改善。它的NLO系数高达134 pm V-1,衰减的起始温度高达150°C。所有这些特性,加上改进的光学透明性,使其成为光子领域实际应用的有希望的候选者。
