Guanosine and fullerene derived de-aggregation of a new phthalocyanine-linked cytidine derivative

Electronic absorption and fluorescence spectroscopies were used to study the aggregation and de-aggregation behavior of a novel cytidine tethered zinc phthalocyanine shown schematically above. De-aggregation of this conjugate, can be effected using guanosine, C60, as well as via the addition of a synthetic guanosine-C60 hybrid.
