摘要

力刺激响应型有机发光小分子因其独特的发光性质在信息加密、光学存储、压力传感器等领域具有潜在应用，引起了广泛关注。其相关发光特性并不只来源于单分子结构，更与分子聚集态不同的堆积模式密切相关，因此，如何调控分子堆积模式是获得功能化发光材料的关键。本文主要从力致变色和力致发光材料体系出发，概述了几种调控分子间相互作用的策略，突出强调了分子堆积与发光性能之间的关系，为研究具有新颖发光特性的发光材料提供了研究思路，希望促进有机发光材料的进一步发展。

Abstract

Mechanical-responsive organic luminogens have potential applications in the fields of information encryption

optical storage

pressure sensors

etc

. due to their unique luminescent properties

and have attracted widespread attention. Their luminescent properties are not only derived from the single-molecule structure

but also closely related to the different stacking modes of molecular aggregates. Therefore

how to control the molecular stacking mode becomes a key issue for obtaining functional luminescent materials. This review mainly focuses on the material system of mechanochromism and mechanoluminescence

outlines several strategies to regulate the intermolecular interactions

and highlights the relationship between molecular stacking and luminescent performance

which paves a new way to design novel luminescence materials and further promotes the development of organic luminescent materials.
