β‐Ketonitrile‐Modified Prodan Derivatives as Large‐Stokes‐Shift Solvatochromic Fluorophores With Enhanced Brightness and Ratiometric Thermometric Response

open access: yesChemistry – A European Journal, EarlyView.
We report a systematic study of β‐ketonitrile–modified Prodan‐type solvatochromic fluorophores. The β‐ketonitrile substitution induces marked bathochromic shifts in absorption and emission and significantly enhances fluorescence quantum yields in nonpolar solvents.

Tailoring Liquid Crystalline Self‐Assembly and Photophysical Properties of Unsymmetrical Fluorenones via Polar Terminal Groups

open access: yesChemistry – A European Journal, EarlyView.
Novel liquid crystalline fluorenones bearing various head groups were synthesized and characterized. By alteration of the head group, N, SmC, or SmA phases were obtained, and emission properties could be tuned depending on solvent or temperature. ABSTRACT In this work, a series of novel unsymmetrical fluorenone derivatives bearing various head groups ...

Europium Doped Atomically Precise Bismuth Oxido Nanoclusters as Molecular Building Blocks for Photoluminescent Hybrid Materials

open access: yesChemistry – A European Journal, EarlyView.
Europium doping of bismuth oxido nanoclusters (BiO‐NCs) provides stable hosts for Eu3+ in an asymmetric coordination environment, which in turn results in an intense 5D0→7F0 transition and long luminescence lifetimes. Transparent hybrid materials showing characteristic red photoluminescence are accessible via radical copolymerisation of these soluble ...

Proximal Steric Shielding Unlocks High Solid‐State Luminescence in Quinoxaline‐Fused Pyrene Heteroacenes

open access: yesChemistry – A European Journal, EarlyView.
Proximal steric tuning of quinoxaline‐fused pyrene heteroacenes enables soluble derivatives that exhibit solid‐state photoluminescence quantum yields (PLQYs) up to 82%, surpassing previous benchmarks. This work reveals key structure–property relationships for next‐generation, processable organic emitters in advanced optoelectronic applications ...

Clathrate hydrate crystallization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Clathrate hydrate crystallization has been an area of interest to chemical engineers from the point of view of crystal structure, thermophysical properties, phase equilibria, kinetics, industrial applications, and environmental (climate change) implications.
