m‑Phenylene-Linked Dipyrrins and Their Boron–Difluoride Complexes as Variously Shaped Macrocyclic Oligomers
dataset
posted on 2016-10-10, 19:44 authored by Junji Uchida, Takashi Nakamura, Masaki Yamamura, Gento Yamaguchi, Tatsuya NabeshimaThe effectiveness
of a m-phenylene linker, which
has rigidity as well as rotational flexibility, is presented to produce
a series of variously shaped macrocyclic oligomers of dipyrrins and
BODIPYs, whose structures were revealed by X-ray crystallography and 1H NMR analysis. Although the chemical structures of the repeating
units are the same for dipyrrin/BODIPY oligomers, their absorbance
and emission properties changed significantly depending on the size
and shape of the macrocycles.
