An Iodinated Cuprous Cluster-Based Coordination Polymer as An Acridine Ligand for Photothermal Materials and with Photothermal Properties and Its Preparation Method and Application

The invention discloses an iodinated cuprous cluster-based coordination polymer as an acridine ligand for photothermal materials and with photothermal properties and its preparation method and application. CuI and 2,7-bis (pyridin-4-yl) acridine are mixed with solvent. After heating reaction, the solid precipitated by cooling is the iodinated cuprous cluster-based coordination polymer. In the invention, œ, B- and y-CuI-DPA with different spatial topologies can be prepared just by adjusting the ratio of metal to ligand using the self-designed and synthesized ligand 2,7-bis (pyridin-4-yl) acridine (DPA). The three iodinated cuprous cluster-based coordination polymers are synthesized for the first time, and CPS With different spatial topologies are also constructed based on the same molecular block for the first time, The synthesized y-CuI-DPA contains rare three- dimensional structure constructed by 6-connect [CuzIz]. Such a unique chain provides a charge transport channel for the three-dimensional structure of y-CuI-DPA, resulting in higher conductivity and photothermal conversion efficiency than those of d-CuI-DPA and B-CuI-DPA, and also lays a foundation for the design and preparation of conductive CPS With metal ion chains.
