资源简介：
Hexameric
and tetrameric porphyrin nanorings, Z6·T6 and Z4·T4, were synthesized
in 53% and 14% yields, respectively, by the Sonogashira-type self-oligomerization
of porphyrin monomer 1 using hexadentate template T6 and tetrapyridylporphyrin template T4. Template-free
nanorings Z6 and Z4 were also prepared.
The femtosecond transient absorption measurements revealed fast excitation
energy hopping (EEH) along these nanorings with hopping rates of 2–5
ps. Treatment of Z6 with chiral template CT6 gave Z6·CT6 showing circular dichroism
(CD) and circularly polarized luminescence (CPL) in the absorption
and fluorescence regions of Z6, respectively, which indicates
chirality transfer from CT6 to Z6.
