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 flurometric method was developed for rapid determination of CV with a good linearity in the concentration range of 1.40-37.4 mu mol L-1. The method was applied for the determination of CV in synthetic samples successfully. (C) 2009 Elsevier B.V. All rights reserved.
