Make the Ylides Shine: Synthesis and Structure-Property Relationships of Phosphasquaraines

Key Points

• The central goal is to synthesize a new family of phospha-squaraine dyes and explore their structure-property relationships.
• Synthesis of four phospha-squaraine dyes from squaric acid derivatives.
• Full characterization of synthesized dyes.
• Analysis of structure-properties relationships.
• Successful synthesis of four distinct phospha-squaraine dyes.
• Characterization revealed specific structural traits influencing optical properties.
• Identified trends in how structure relates to the functional qualities of the dyes.
