Themed collection The 1st Sauvage Symposium

Recent progress in organic luminogens modified with alkyl groups and their corresponding emissive properties are summarized in this review, which can be depicted by the concept of Molecular Uniting Set Identified Characteristic (MUSIC).

Introducing photochromic units into the electronic material system allows the reversible tuning of the output signals of a photochromic OFET by light triggers, resulting in a remote-controllable device with potential applications.

Schematic diagram of NIR J-aggregates of various organic dyes as effective bioimaging (fluorescence (FL) or photoacoustic (PA)) and therapeutic agents (PDT or PTT).

This minireview summarizes advances in the molecular design strategy and biological applications of fluorescent probes for β-galactosidase (β-Gal), focusing on detection accuracy enhancement and aggregation-induced emission for background minimization.

Herein, the latest progress of AIEgens for application in wash-free detection and bioimaging was reviewed.

Facilitated by Pt⋯Pt, π–π stacking and hydrophobic interactions, a new series of dinuclear anthracene-containing alkynylplatinum(II) terpyridine complexes is found to exhibit intriguing photo-modulated self-assembly behaviors upon photooxygenation.

This research revealed a class of fluorescent materials which have a response to humidity, based on simple small molecules via a CB[8]-based supramolecular assembly strategy, in which the materials’ fluorescent properties can be dynamically controlled.

This work reports the cooperative photocatalysis of a two-dimensional covalent organic framework with an electron transfer mediator in a selective organic transformation.

In this article, well-defined radical metallacycles were efficiently constructed through coordination-driven self-assembly, which displayed interesting chiral self-sorting behavior as well as very weak radical-based luminescence.

Water-soluble hydrazone-connected 3D flexible organic frameworks have been revealed to in situ load and deliver short DNA into normal and cancer cells.

A covalently encapsulated dual-dye silica nanoprobe has been developed by a one-pot approach for sensitive ratiometric hypoxia detection with the K_sv value of 243.1 bar⁻¹ and I₀/I₁₀₀ ratio of 153.

We use nonporous adaptive crystals of perethylated pillar[6]arene to adsorb heterocyclic compounds from a mixture of toluene and heterocyclic compounds with high selectivity, ultimately improving the purity of toluene from 96.78% to 99.00%.

The introduction of mechanical functions and controlled motion based on molecular motors and machines offers tremendous opportunities towards the design of dynamic molecular systems and responsive materials.
