摘要

Abstract

Efficient detection of nitroaromatic explosives remains a great challenge

and covalent organic frameworks (COFs) incorporating aggregation-induced emission (AIE) units provide a promising platform for high-performance fluorescent sensing. Herein

we designed and synthesized both

two-dimensional (2D) and three-dimensional (3D) AIE-active COFs to systematically investigate how dimensional differences (pore architecture

charge transfer efficiency

and AIE behavior) regulate sensing performance. Through a “4+4” imine condensation strategy

a 2D sql topological COF (TPPDA-TPTPE) was obtained from a planar tetraamine (TPPDA)

whereas a 3D

pts

topological COF (JUC-646) was constructed from a twisted tetraamine (BMTA) with

geometry—using the same TPTPE linker. Both COFs exhibit high crystallinity

stability

and strong AIE-derived luminescence

but show strikingly different sensing performances. In particular

JUC-646 achieves a quenching constant of 6.99×10

L/mol toward 2

6-trinitrophenol (TNP)

nearly five times higher than that of TPPDA-TPTPE. This superior performance originates from the 3D open-channel structure (facilitating analyte diffusion)

enhanced host-guest interactions

and energetically favorable photoinduced electron transfer—all of which are derived from dimensional differences. This comparative study explicitly establishes a structure-function relationship between framework dimensionality and sensing performance

offering direct guidance for the rational design of AIE-active COFs with tailored dimensionality for efficient explosive detection.
