A generalized supramolecular strategy for self-sorted assembly between donor and acceptor gelators

Area of Science:

• Supramolecular Chemistry
• Materials Science
• Organic Chemistry

Background:

• Organogelators are molecules that can form gels in organic solvents.
• Self-sorting is a process where different molecules spontaneously separate into distinct phases.
• Controlling the self-assembly of molecules is crucial for designing advanced materials.

Purpose of the Study:

• To develop an effective supramolecular strategy for the self-sorting of naphthalene-diimide (NDI) acceptor and dialkoxy-naphthalene (DAN) donor organogelators.
• To investigate the role of amide functional group placement in directing self-sorting behavior.

Main Methods:

• Design and synthesis of NDI acceptor and DAN donor organogelators with specific amide placements.
• Experimental investigation of self-sorting behavior in solution and gel states.
• Spectroscopic and microscopic techniques to analyze molecular interactions and self-assembled structures.

Main Results:

• An effective self-sorting strategy was achieved between NDI acceptors and DAN donors.
• Mismatch in amide functionality placement was identified as the key factor driving self-sorting.
• The strategy ensured maximum hydrogen bonding interactions, leading to efficient separation.

Conclusions:

• The reported supramolecular strategy provides a novel approach for controlling the self-assembly of organogelators.
• This work demonstrates the potential of precisely controlling molecular architecture to achieve selective self-sorting.
• The findings have implications for the design of complex supramolecular systems and functional materials.
