ABSTRACT

The existence of long, directional interactions (LDI) was proposed based on structural analyses of cofacial oligomeric siloxysilicon phthalocyanines. It was further extended to siloxygermanium phthalocyanines. Silicon and germanium phthalocyanine centers were selected for a number of beneficial properties, a premier property being their diamagnetism. A wider study to the LDI investigation shows a number of transition metal phthalocyanines that appear to exhibit the same structural behavior. Therefore, building on this work, this current study explores the potential of titanium as a suitable metal center for dimeric cofacial axial functionalized phthalocyanines. Through detailed spectroscopic analysis, the study aims to evaluate how the introduction of these alternative metals influences the geometry, electronic environment, and stability of the cofacial systems, attempts to strengthen the evidence for LDI bonds in dimeric cofacial systems, and opens pathways for their broader application in the design of multifunctional materials and coordination architectures.
