The effect of substitutents at alkylsulfanyl/arylsulfanyl non-peripherally substituted phthalocyanines: Spectral and photophysical properties, basicity and photostability
The effect of substitutents at alkylsulfanyl/arylsulfanyl non-peripherally substituted phthalocyanines: Spectral and photophysical properties, basicity and photostability
The effect of phthalocyaninemacrocycle distortion on its spectroscopic and packing properties is studied, by comparing two phthalocyanines octa-non-peripherally substituted by alkanethiols of different bulkiness (n-hexyl and tert-butyl). Their X-ray structures evidence their core shape, respectively planar and strongly distorted, inducing a 55 nm shift of their maximum absorption wavelength. Comparison
Three tert-butylsulfanylphthalonitriles have been prepared with optimized synthetic procedures. Their comparative structural analyses have been completed, with a focus on IR and NMR spectroscopy and refined X-ray structural data. Miscellaneous parameters such as UV absorption, melting points, and related polarity of the compounds are summarized.
