Organic luminescent materials hold significant promise for applications in modern technology. Traditionally, their design has been guided by π-conjugation theory. However, the recent discovery of weak interactions-based luminescent materials, such as multiarylalkanes (MAAs), has challenged this paradigm. Emerging research suggests that these materials emit light from through-space conjugation (TSC), including π-π, n-π, and n-n TSC. Owing to their well-defined structures and facile chemical modification, MAAs serve as ideal models for investigating TSC. This review systematically examines the mechanisms of TSC in these systems from three key perspectives: conformational regulation, donor-acceptor (D-A) and n-electronic modulation. Studies on their photophysical processes reveal that conformational control and D-A electronic modulation predominantly influence emission through π-π TSC. In contrast, tuning the n-electron structure, particularly involving lone pair electrons on nitrogen atoms, introduces n-π and n-n TSC, enabling red-shifted emission and enhanced luminescence efficiency. By providing a comprehensive analysis of TSC in MAAs, this review refines the current understanding of TSC-based luminescence and offers valuable design principles for developing novel, highly efficient, weak interactions-based luminescent materials.
