资源简介：
Hexadecadehydrodibenzo[20]-, tetracosadehydrotribenzo[30]-,
and
dotriacontadehydrotetrabenzo[40]annulene derivatives ([20]-, [30]-,
and [40]DBAs) possessing tetrayne linkages were synthesized. X-ray
diffraction analysis demonstrated that the molecules of [30]DBA and p-xylene form a 2D sheetlike structure. Planar [20]- and
[30]DBAs show significantly weak or almost no tropicity. The extension
of the acetylenic linkages from a diyne to a tetrayne unit narrows
HOMO–LUMO gaps. The self-association behavior of [30]DBA in
solution resulting from effective π–π stacking
interactions was observed.
