Nanoscalar Platinaprisms designed from triptycene based organometallic complexes

What is it about?

Synthesis of two new triptycene based polytopic Pt(II) organometallic complexes is described. These were used as building block in construction (via coordination driven self-assembly) of metallasupramolecular cages possessing six units of positive charges. To the best of our knowledge, self-assembled metallacages reported herein are the only examples of triptycene based supramolecular distorted and trigonal nano-dimensional “platinaprisms” containing triptycene motifs.

Why is it important?

This study provides a facile synthetic route for for the efficient synthesis of triptycene unit containing three dimensional supramolecular framework via "coordination driven self-assembly" approach. Additionally, the triptycene based organometallic complexes reported herein aim to enrich the molecular library of metal based acceptors used as building blocks (supramolecular synthons) in directional bonding approach.
