Giant Enhancement of Optical Nonlinearity by Manipulating Guest Molecular Stacking Modes in Metal–Organic Frameworks

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: March 4, 2025

The influence of guest stacking interactions in host-guest (H-G) MOF composites on third-order nonlinear optical (NLO) performance remains largely unknown. Herein, we propose for the first time a noncovalent aggregate confinement strategy synthesizing H-G with different modes. And [perylene2]n (α-Pe) and [perylene]n (β-Pe) were selected as guests confined into novel Ca-based {[Ca(TBAPy)(DMA)2]·3DMA·[N(CH3)2]·H2O}n (Ca-MOF-pts). NLO results showed that compared to β-Pe@Ca-MOF-pts, saturable absorption (SA) self-defocusing properties α-Pe@Ca-MOF-pts increased by 2.71-fold 3.82-fold, respectively. Interestingly, α/β-Pe@Ca-MOF-pts can be transformed α/β-Pe@Ca-MOF-flu (Ca-MOF-flu = {[Ca1.5(TBAPy)(H2O)2]·DMA·[N(CH3)2]·2H2O}n) through self-adaptive topological evolution, corresponding signal change from SA reverse (RSA). As expected, β-Pe@Ca-MOF-flu, RSA α-Pe@Ca-MOF-flu are improved 2.94-fold 4.07-fold, respectively, demonstrating importance Theoretical calculation transient spectra indicated enhancement was attributed large π-π overlap α-Pe, which promoted electron delocalization/transfer optimized cross-sectional ground state excited state. This study provides new developing excellent properties.

Bimetallic metal–organic frameworks (MOFs) capable of sensing external stimuli will provide more possibilities for further regulating third-order nonlinear optical (NLO) properties. In this work, we synthesized bimetallic MOFs (ZnCu-MOF and ZnCd-MOF) through central metal exchange using a photoresponsive Zn-MOF as precursor. Compared with Zn-MOF, both ZnCu-MOF ZnCd-MOF exhibit significantly enhanced NLO absorption This is mainly attributed to the introduction ions different electron configurations that can adjust bandgap enhance delocalization, thus promoting transfer.

Specifically, incorporated tetrakis(4-carboxyphenyl)porphyrin (TCPP) with an exceptionally electron-rich delocalization system into framework using one-pot solvothermal method, ingeniously occupying partial distribution sites Zr6 clusters. Compared UiO-66, NLO absorption refraction performance TCPP/UiO-66 were significantly improved. Additionally, due presence nitrogen-rich that can accommodate metal ions porphyrin ring TCPP, Co(II), Ni(II), Cu(II), Zn(II) are introduced TCPP/UiO-66, extending d–π conjugation effect further regulate The behavior transforms saturation (SA) reverse (RSA), while shifts from self-defocusing self-focusing.
