A Crystalline 3D Supramolecular Polymer Constructed by Clamparene-Based Controllable Self-Assembly and Its Application in Photothermal Conversion

The development of well-defined three-dimensional supramolecular
polymers presents significant challenges, particularly in achieving
crystalline state structures. This study addresses this challenge
by presenting the construction of a crystalline three-dimensional
supramolecular polymer through the self-assembly of clamparene (CLP) and a naphthalene diimide derivative (NDIOH) in the solid state. The hierarchical self-assembly progresses from
one-dimensional linear supramolecular polymers to two-dimensional
supramolecular polymers and ultimately to a crystalline three-dimensional
supramolecular polymer. Moreover, the prepared crystalline three-dimensional
supramolecular polymer demonstrates effective photothermal conversion.
This work advances the understanding and design of functional three-dimensional
supramolecular polymers in the crystalline state.
