Molecules Engineering of Continuous Self‐Assembled Photonic Crystal Films from Fluorene‐Based Ortho‐Linkage Gridization Nanopolymer
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.
