Coordination-driven self-assembled container molecules are now well known for guest binding and encapsulation. In last two decades, template effect in the fine-tuning and reorganisation of self-assembly has also been reported. We recently reported the interlocked and non-interlocked molecular dimers self-assembled with tetracene-Ru(II) p-cymene based acceptor and linear dipyridyl donors.1-2 In this poster we will present the self-assembly of similar Ir(III) based catenane and non-catenane rectangles. Template and solvent effect on the catenane and non-catenane structures was compared with known Ru(II) analogues. New self-assembled architectures were fully characterized using various spectroscopic techniques and 2D NMR as well. The structures were confirmed using single crystal X-ray analysis also.
