“…Some types of dendrimer, namely the so-called light-harvesting dendrimers, have attracted considerable interest because the optical energy absorbed in the periphery is transferred to the core, and a significant amount of energy can be concentrated at the core [1,2]. This light-harvesting property would be useful for realizing molecular-based devices such as low-threshold lasers [3], light frequency converters [4], optical switches [5][6][7], and biomimetic systems for photosynthesis [8][9][10]. Despite this high level of interest, the mechanism of the light-harvesting mechanism has not been understood completely, and no first-principles dynamics simulation has been performed so far on this subject.…”

Carrying out a semi-classical Ehrenfest dynamics simulation based on the time-dependent density functional theory, we investigate the light-harvesting property of a π-conjugated dendrimer, star-shaped stilbenoid phthalocyanine (SSS1Pc) with oligo (p-phenylenevinylene) peripheries and show that an electron and a hole transfer from the periphery to the core through a π-conjugated network when an electron is selectively excited in the periphery. The one-way electron and hole transfer occurs more easily in dendrimers with a planar structure than in those with steric hindrance because π-conjugation is well maintained in the planar structure. The present results explain recent experiments.
