Spectrofluorometric studies on the interaction between oxacalix[6]arene-locked trizinc(II)porphyrins and crystal

Abstract:
A new fluorogenic oxacalix[6]arene bearing three zinc(II) porphyrin groups (1) was prepared. When crystal violet (CV) was bound to 1, fluorescence intensity of 1 was quenched regularly. This indicates that 1 and CV formed a 1:1 complex and the association constant was calculated. The inclusion mechanism was also discussed. This new fluorometric method was developed for rapid determination of CV with a good linearity in the concentration range of 1.40-37.4 micromolL(-1). The method was applied for the determination of CV in synthetic samples successfully.

However, the stretching absorptions for the C=O bond vary depending on the structure of carboxylic acids. The C=O bond of the free carboxylic acids shows a higher stretching frequency, 1760 cm−1, while H-bonded carboxylic acids (dimers) exhibit stretching absorptions at a lower frequency, 1710 cm−1. The C=O bond of the...
