A near-infrared fluorescent phthalocyanine liquid developed through controlling intermolecular interactions

Novel liquid phthalocyanines 1 and 2 were synthesized, and the correlation between their molecular structure and intermolecular interactions in the solvent-free state was investigated. H-aggregates were formed in 1 , and a monomeric non-aggregate state emitting in the near-infrared (NIR) spectral ra...

Description
Summary:Novel liquid phthalocyanines 1 and 2 were synthesized, and the correlation between their molecular structure and intermolecular interactions in the solvent-free state was investigated. H-aggregates were formed in 1 , and a monomeric non-aggregate state emitting in the near-infrared (NIR) spectral range was developed in 2 , enabling its application in NIR-technology. A near-infrared fluorescent phthalocyanine (Pc) liquid was developed through introducing bulky yet flexible units onto the Pc skeleton.
