Abstract

The integration of organic light-emitting polymers with photonic crystals (PhCs) presents a compelling platform for achieving enhanced light outcoupling efficiency, representing a significant advancement in the development of efficient PLEDs and ASE emitters. Herein, a direct oriented molecular design strategy for mesoscale self-assembly under ambient conditions is demonstrated, successfully fabricating photonic crystals (PhCs) through 1D linear structure fluorene-based nanopolymers. This ordered self-assembly exhibits typical angular-resolved Bragg-Snell diffraction behavior. Notably, the PhC films demonstrate substantial performance improvements, with the current efficiency rising from 0.50 to 0.75 cd A⁻¹, while the threshold for amplified spontaneous emission through self-assembly is significantly reduced from 105.05 to 48.46 kW cm⁻². This nanogridization-driven approach to organic polymer semiconductors opens new avenues for cross-scale molecular design, offering promising opportunities for the development of multifunctional and intelligent light displays.

芴基正交键化纳米聚合物连续自组装光子晶体膜的分子工程

有机发光聚合物与光子晶体（PhCs）的集成为实现增强光解耦效率提供了一个引人注目的平台，代表了高效led和ASE发射器的发展取得了重大进展。本文展示了一种在环境条件下进行中尺度自组装的直接定向分子设计策略，成功地通过一维线性结构芴基纳米聚合物制造光子晶体（PhCs）。这种有序自组装表现出典型的角分辨布拉格-斯涅尔衍射行为。值得注意的是，PhC薄膜表现出了显著的性能改善，电流效率从0.50提高到0.75 cd A−1，而通过自组装放大自发辐射的阈值从105.05显著降低到48.46 kW cm−2。这种纳米化驱动的有机聚合物半导体方法为跨尺度分子设计开辟了新的途径，为多功能和智能光显示器的发展提供了有希望的机会。
