<P>PROBLEM TO BE SOLVED: To provide an emissive multichromophoric system based on new highly conjugated porphyrin. <P>SOLUTION: A compounded multichromophoric system is provided, which shows excitation state of low energy fluorescence correlated with a phase relation, by which a transition dipole of a formation block of a pigment is designated. Polarized property of these singlet excitation state can be preserved with a long temporal measure (units in ns). In a preferred embodiment, ethylene- and butadiene-bridged multiporphyrin speices showing high anisotropic excitation state shows an exceptionally large light-emitting dipole intensity, and it is a new example for oligo pigment assembly having super radiation luminescence. <P>COPYRIGHT: (C)2007,JPO&INPIT |
