The vibrational Raman spectra of several series of aromatic and quinoidal compounds have
been analyzed considering the downshifts and upshifts of the frequencies of the relevant …

In this article, some quinoidal p-quinodimethanes compounds that convert partially or
completely to diradicals or biradicaloids are analyzed. The aromatic/quinoidal balance is …

Development of high-performance unipolar n-type organic semiconductors still remains as a
great challenge. In this work, all-acceptor bithiophene imide-based ladder-type small …

The preparation of a series of dibenzo-and tetrabenzo-fused fluoreno [3, 2-b] fluorenes is
disclosed, and the diradicaloid properties of these molecules are compared with those of a …

Thin film organic lasers represent a new generation of inexpensive, mechanically flexible
devices for spectroscopy, optical communications and sensing. For this purpose, it is desired …

BN‐embedded oligomers with different pairs of BN units were synthesized by electrophilic
borylation. Up to four pairs of BN units were incorporated in the large polycyclic aromatic …

Linearly conjugated systems have long served as an archetype of conjugated materials, but
suffer from two intrinsic structural problems: potential instability due to intermolecular …

We designed and synthesized a series of diarylaminoanthracenes in which the planarity of
the diarylamine moiety is controlled by methylene-or ethylene-bridges. The X-ray …

Conspectus The modern history of conducting organic systems started with a fortuitous error
in 1967 on acetylene polymerization, followed by a rational discovery in 1976 on the effects …

A ladder-type dithieno [3, 2-b: 6, 7-b′] fluorene (DTF), where the central fluorene is fused
with two outer thiophene rings at its 2, 3-and 6, 7-junctions, is developed. The pentacyclic …
