摘要

众所周知,在包光体的化学合成过程中,大量使用二甲基甲酰胺(DMF)和二甲基亚砜(DMSO)等有毒且易挥发的溶剂会带来一些可持续发展的挑战,严重阻碍了其商业应用的大规模生产。本文介绍了一种可聚合的单体溶剂(4-丙烯酰吗啉,ACMO),它可以通过原位聚合实现包光体量子点(PQDs)的生长和光学光刻。形态、结构和光学分析表明,这种可聚合单体既可以作为溶解包晶前驱体的溶剂,也可以作为光聚合反应的单体,从而实现 PQDs 的直接原位制造和图案化。通过直接光刻技术,成功展示了具有高光量子产率、高分辨率(最小尺寸为 5 微米)和优异荧光均匀性的彩色 PQD 图案。这项工作为使用可聚合单体溶剂原位图案化 PQD 提供了一种新的可持续方法,从而在光子、能量收集和光电器件等各种集成应用中取得重大进展。

Polymerizable Monomer Solvents Enabled Direct In Situ Photolithography of Perovskite Quantum Dots

Polymerizable Monomer Solvents Enabled Direct In Situ Photolithography of Perovskite Quantum Dots

The heavy use of toxic and volatile solvents such as dimethylformamide (DMF) and dimethylsulfoxide (DMSO), in the chemical synthesis of perovskites is known to pose several sustainability challenges that significantly hinder their mass production for commercial applications. Herein, a polymerizable monomer solvent (4-acryloylmorpholine, ACMO) is introduced that permits the growth and optical lithography of perovskite quantum dots (PQDs) through in situ polymerization. Morphological, structural, and optical analyses show that this polymerizable monomer can act both as a solvent to dissolve the perovskite precursor and as a monomer for photopolymerization reactions, allowing direct in situ fabrication and patterning of PQDs. By direct photolithography, colorful PQD patterns with high photoluminescent quantum yields, high resolution (minimum size of 5 µm), and excellent fluorescence uniformity, are successfully demonstrated. The work provides a new sustainable way of in situ patterning PQDs using polymerizable monomer solvents, leading to significant advances in various integrated applications, such as photonic, energy harvesting, and optoelectronic devices.
