▎ 摘 要
Pyrene-derivatized H-2, GaCl, and Zn porphyrins were immobilized on graphene quantum dots (GQDs) to form (GQDs-H2TPrP, GQDs-GaClTPrP, and GQDs-ZnTPrP) conjugates through the pi-pi stacking interaction method followed by encapsulating into Pluronic F127 micelles to form (GQDs-H2TPrP F127, GQDsGaClTPrP + F127, and GQDs-ZnTPrP F127). Spectroscopic evidence shows that the resultant conjugates were stable due to the strong pi-pi stacking interaction between the GQDs and the porphyrins. The fluorescence and singlet oxygen generating behaviour of the porphyrins were investigated following incorporation. GQDs-GaClTPrP + F127 showed highest values of the binding constant (K-b). The Stern-Volmer constant (K-sv) for GQDs-ZnTPrP F127 were the highest compared to other porphyrins derivatives. (C) 2017 Elsevier Ltd. All rights reserved.
