Overview

Randomized trial demonstrates switchable luminescence in different supramolecular arrangements, implying new applications.

Key Points

  • The study aims to explore the photoluminescence properties of a 1,8-naphthalimide derivative through polymorphism and mechanochromism.
  • Investigated crystallization conditions to produce different supramolecular arrangements.
  • Studied conversion of polymorphs through mechanical grinding and heating.
  • Analyzed emission behavior across various polymorphs and pseudopolymorphs.
  • All polymorphs exhibited distinct emission maxima between 551 nm and 577 nm.
  • Physical processes like grinding allowed for interconversion between different polymorphs.
  • Demonstrated potential for multi-stimulus-responsive luminescent materials.
