Area of Science:

• Organic Chemistry
• Biophysics
• Microscopy

Background:

• Chirality plays a crucial role in biological processes.
• Current bioimaging techniques often lack the ability to detect or analyze chirality.
• Circularly polarized luminescence (CPL) offers a potential method for chiral detection in biological systems.

Purpose of the Study:

• To develop novel, small, full-organic probes for CPL bioimaging of live cells.
• To advance Circularly Polarized Luminescence Laser-Scanning Confocal Microscopy (CPL-LSCM) for biological applications.
• To investigate the role of chirality in biological processes using CPL-bioimaging.

Main Methods:

• Design and synthesis of BODIPY-based organic probes functionalized with a BINOL moiety.
• Characterization of probe properties, including CPL emission and biocompatibility.
• Application of the probes in live-cell bioimaging using CPL-LSCM and multiphoton microscopy.

Main Results:

• Successful development of the first small, full-organic probes for CPL-bioimaging of live cells.
• Demonstration of probes' high biocompatibility and adaptability for CPL-LSCM.
• Probes exhibited multiphoton (MP) activity, enabling MP-CPL-bioimaging.
• The BODIPY-BINOL scaffold proved effective for achieving tunable CPL emissions.

Conclusions:

• The developed BODIPY-BINOL scaffold provides a simple and accessible design for efficient CPL probes.
• These probes are valuable tools for distinguishing, monitoring, and understanding chirality in biological systems.
• The advancement of MP-CPL-bioimaging opens new avenues for chiral biological research.
