Ultrafast responses of doubly N-confused hexaphyrin derivatives

Confused hexaphyrin derivatives, which are remarkable as the organic optical materials for information processing technology, have been synthesized. Hexaphyrin derivatives, free base type, substituted one and metal complex were studied in view of photophysical properties. The effects of pi-conjugation have been studied by measuring of absorption and fluorescence spectra. They were excited by femtosecond pulsed laser to see the photoresponsibility and dynamics. Instantaneous changes, transient bleaching or transient absorption, will be discussed in the visible region.Confused hexaphyrin derivatives, which are remarkable as the organic optical materials for information processing technology, have been synthesized.
