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

Chemistry – 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.

Seats at the Table, Shifts in the Actions: Board Gender Diversity and Climate Activism

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT As regulatory and stakeholder pressures intensify, firms are increasingly expected to move beyond symbolic sustainability commitments towards corporate climate activism. This concept refers to the active institutionalisation of climate‐focused mechanisms such as external assurance, board oversight and climate‐linked incentives.
