Semiconducting polymers (SPs) are a fascinating class of organic materials that have led to significant discoveries in recent decades. In addition to possessing excellent charge transport properties, SPs are synthetically versatile, offering a myriad of possibilities to fine-tune their optoelectronic, thermomechanical, and solid-state properties. Despite these unique features, the application of semiconducting polymers for the fabrication of next-generation electronics has been limited. Among others, CPs have a limited stability to the complex microfabrication processes often required to fabricate advanced electronics. This severely limits the manufacturing of new electronics.To address this challenges, this research will focus on the development of a novel strategy to access photopaternable, robust and efficient SPs through the formation of polydiacetylene (PDA) crosslinks. The formation of PDA is a highly specific solid-state reaction, which can be selectively used to pattern high resolution features (few nanometers) towards the fabrication of novel electronic devices. Additionally, formation of PDA introduces potential new charge transport pathways across the polymeric network, which will enhance the optoelectronic properties of the materials. Through a unique international multidisciplinary partnership, interlacing materials chemistry, organic electronics, and materials sciences, our team will unveil the influence of PDA crosslinks on the thermomechanical and optoelectronic properties of high molecular weights SPs by a meticulous multimodal characterization strategy. Based on the new knowledge gained, our team will use the new materials to pattern thin films into nanoscopic devices, thus highlighting their potential for the fabrication of advanced organic electronics with mechanical robustness and enhanced efficiency. From a global perspective, this unique international and multidisciplinary partnership will act as a catalyst for the establishment of this new approach while providing a cutting-edge training for the next generation of highly skilled Canadian scientists.

半导体聚合物（SP）是一类迷人的有机材料，在近几十年来引起了重大发现。除具有出色的电荷传输特性外，SP在合成的多功能上还具有多种可能性来微调其光电，热力学和固态特性。尽管有这些独特的特征，但是将半导体聚合物应用于下一代电子产品的制造受到限制。除其他外，CP的稳定性有限，通常需要制造高级电子产品。这严重限制了新电子产品的制造。为了应对这一挑战，这项研究将着重于通过形成聚乙烯（PDA）交叉链接的新型策略的开发，以获取可获得光的策略。 PDA的形成是一种高度特定的固态反应，可以选择性地用于将高分辨率特征（少量纳米）用于制造新型电子设备。此外，PDA的形成引入了整个聚合物网络的潜在新电荷传输途径，这将增强材料的光电特性。通过独特的国际多学科合作伙伴关系，交织材料化学，有机电子和材料科学，我们的团队将通过精致的多媒体表征策略揭示PDA交叉链接对高分子量SP的热机械和光电特性的影响。基于获得的新知识，我们的团队将使用新材料将薄膜将薄膜模式化为纳米镜设备，从而突出了它们以机械鲁棒性和提高效率来制造高级有机电子产品的潜力。从全球角度来看，这种独特的国际和多学科伙伴关系将成为建立这种新方法的催化剂，同时为下一代高技能的加拿大科学家提供尖端的培训。
