The modulation effect of an electron-rich guest on the luminescence of naphthalene diimide-based metal–organic frameworks

Abstract

A series of host–guest MOF materials were successfully fabricated by virtue of donor–acceptor interactions, which exhibit color-tunable emissions in a wide wavelength range by rational selection of guest molecules.

Confinement of Pyridine Derivatives into a Metal–Organic Framework Host as Electron Acceptors to Achieve Photoinduced Electron-Transfer

“…In the past decades, MOFs with guest-dependent character have been explored in chemical sensing, molecular recognition, photochromism, and so forth. − Typically, luminescent, catalytic, photochromic guests, etc., are usually adopted to construct such MOFs. However, examples of constructing functional host–guest complexes by assembling nonfunctional solvent molecules into a MOF host are relatively few.…”

Hierarchical self-assembly of a radical naphthalenediimide-based N-heterocyclic carbene-Au(i) macrocycle

“…Pyrene and naphthalene have been recognized as representative electron-rich polycyclic aromatic hydrocarbons, which possess extensive π-electron delocalization. 42,43 In contrast, NDI-based macrocycle [Au-1]BF 4 is an excellent electron acceptor that features electron-withdrawing imide groups on planar aromatic naphthalene and has a strong tendency to interact with electron donors. When pyrene was added to a DMF solution of [Au-1]BF 4 , a noticeable color change of the mixture from yellow to red was observed.…”

The effect of conjugation degree of aromatic carboxylic acids on electronic and photo-responsive behaviors of naphthalenediimide-based coordination polymers

“…More importantly, the change of the frameworks affords a strong possibility for the generation of diversified interfacial contacts of EDs/EAs and subsequent distinguishing intermolecular electronic behaviors. [55][56][57][58][59] Therefore, the combination of flexible electrondeficient NDI with different electron-rich auxiliary ligands is an effective strategy for modulating the interfacial relationship of EDs/EAs as well as providing a great chance to ascertain the influence mechanism of ICT on PIET.…”
