Název v původním jazyce

The effect of substitutents at alkylsulfanyl/arylsulfanyl non-peripherally substituted phthalocyanines: Spectral and photophysical properties, basicity and photostability

Popis výsledku v původním jazyce

A series of magnesium, zinc and metal-free derivatives of non-peripherally substituted phthalocyanines (Pcs) bearing alkylsulfanyl or arylsulfanyl groups of different bulkiness was synthesized. Their spectral and photophysical properties including also the basicity of azomethine nitrogens and photostability were compared within the series as well as with similar peripherally substituted Pcs. Non-peripheral position of substituents led to the 70 nm red-shift of Q-band in comparison to the peripherally substituted Pcs. However, unexpected blue-shift of approximately 50 nm was observed in the series of non-peripherally substituted Pcs for the most bulky tert-butylsulfanyl derivative caused probably by extreme distortion of the macrocycle. The substitutionhad no effect on photophysical properties and compounds reached Phi(Delta) values 0.74-0.76 and Phi(F) 0.053-0.080 for zinc complexes, and Phi(Delta) 0.47-0.51 and Phi(F) 0.10-0.17 for magnesium complexes following the rule of heavy atom
