Guest-adaptive molecular sensing in a dynamic 3D covalent organic framework

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: Dec. 24, 2022

Molecular recognition is an attractive approach to designing sensitive and selective sensors for volatile organic compounds (VOCs). Although macrocycles cages have been well-developed recognising organics by their adaptive pockets in liquids, porous solids gas detection require a deliberate design balancing adaptability robustness. Here we report dynamic 3D covalent framework (dynaCOF) constructed from environmentally fluorophore that can undergo concerted structural transitions upon adsorption of vapours. The COF capable rapid reliable various VOCs, even non-polar hydrocarbon under humid conditions. guest inclusion amplifies the host-guest interactions facilitates differentiation vapours polarity sizes/shapes, covalently linked interwoven networks ensure robustness coherency materials. present result paves way multiplex fluorescence sensing VOCs with molecular-specific responses.

Optical Phenomena in Molecule-Based Magnetic Materials

Chemical Reviews, Journal Year: 2024, Volume and Issue: 124(9), P. 5930 - 6050

Published: April 30, 2024

Since the last century, we have witnessed development of molecular magnetism which deals with magnetic materials based on species, i.e., organic radicals and metal complexes. Among them, broadest attention was devoted to molecule-based ferro-/ferrimagnets, spin transition materials, including those exploring electron transfer, nanomagnets, such as single-molecule magnets (SMMs), qubits, stimuli-responsive materials. Their physical properties open application horizons in sensors, data storage, spintronics, quantum computation. It found that various optical phenomena, thermochromism, photoswitching characteristics, luminescence, nonlinear chiroptical effects, well responsivity external stimuli, can be implemented into Moreover, fruitful interactions these effects provide new cross-effects multifunctionality, enriching applications optical, electronic, devices. This Review aims show scope phenomena generated recent advances areas high-temperature photomagnetism, thermometry utilizing SMMs, addressability magneto-chiral dichroism, opto-magneto-electric multifunctionality. These findings are discussed context types accessible for classes
