Two-dimensionally extended, polycyclic heteroaromatic molecules (heterocyclic
nanographenes) are a highly versatile class of organic materials, applicable as functional …

Various heterocyclic systems based on natural and unnatural biologically active products
were synthesized by Brønsted acid-promoted cyclization. We have made an attempt to …

The concepts of excited-state aromaticity and antiaromaticity have in recent years with
increasing frequency been invoked to rationalize the photochemistry of cyclic conjugated …

Progresses in the design and application of conjugated small molecules, oligomers and
polymers have empowered rapid development of organic electronic technology as an …

In this Feature Article, we report a family of organic semiconductors based on isomeric
naphthodithiophenes (NDTs). The small-molecule-and polymer-based organic …

Three regioisomeric sulfur-bridged pyrene–thienoacenes (PTAs) have been synthesized.
The crystal structures and optoelectronic properties of these ring-fused PTAs and their ring …

Fully aromatic, organic polymers have the advantage of being composed from light,
abundant elements, and are hailed as candidates in electronic and optical devices “beyond …

A facile preparation of benz-annulated heterocycles were achieved at rt involving a Lewis
acid/Brönsted acid mediated annulation of heterocycles using 2, 5 …

Naphthothiophenes were prepared from commercially available 2, 3-dibromothiophenes in
two steps by one-pot Suzuki/Sonogashira or Sonogashira/Suzuki coupling reactions …

A new approach to the synthesis of fused benzothiophene derivatives was developed based
on iodine-promoted photocyclization of 4, 5-diaryl-substituted thiophenes obtained in three …
