The development of water-soluble hexanuclear cluster complexes of low toxicity is a promising task due to their potential biomedical applications such as bioimaging and photodynamic therapy. Herein, we present the syntheses of two new water-soluble hexarhenium cluster complexes with terminal amphiphilic phosphine ligands, and delineate their photoluminescence and X-ray excited optical luminescence (XEOL) properties. These cluster complexes, namely [{Re 6 Q 8 }(PPh 2 CH 2 CH 2 COO) 6 ] 4- (Q = S (1); Se, (2)), have the least cytotoxicity among all the tested hexanuclear metal-clusters, are capable of penetrating into cells and exhibit moderate photodynamic toxicity toward Hep-2 cells.
