 note = {application/pdf, We investigate rapid energy transfer (ET) and its temperature dependence in a star-shaped stilbenoid phthalocyanine (SSS1Pc) dendrimer havingπ-conjugated light-harvesting(LH)antennas, and develop an appropriate model. In SSS1Pc, an intense core photoluminescence (PL) band appears under the selective excitation of the absorption bands of the LH antenna due to highly efficient ETat room temperature(RT). The transient response of core-absorption bleaching and the temporal behaviours of the PL intensities of the core and antenna reveal that ET from the LH antenna occurs rapidly prior to achieving quasi-equilibrium in the photoexcited state of the LH antenna. In addition, it is also clarified that the ET quantum efficiency in SSS1Pc degrades at temperatures.},
