In the broad family of heteropentalenes, the combination of two five-membered heterocyclic
rings fused in the [3, 2-b] mode has attracted the most significant attention. The relatively …

The excited state symmetry breaking charge transfer (SBCT) dynamics of two diacetylide-
triphenylamine (DATPA) derivatives with different electron-donating abilities are investigated …

The phenomenon of excited-state symmetry breaking is often observed in multipolar
molecular systems, significantly affecting their photophysical and charge separation …

The development of organic nonlinear optical (NLO) chromophores is vital for various fields
such as two-photon biomedical imaging, optical limiting, etc. In this work, two bis-chalcone …

A new flexible Zn-based metal–organic framework (IAM-9) containing a tetraarylpyrrolo [3, 2-
b] pyrrole (TAPP) dicarboxylate linker has been synthesized when using DEF as the solvent …

Dihydropyrrolo [3, 2-b] pyrrole (DHPP) skeleton is comprised of only two fused pyrrole rings
and yet, in non-fused form, it had to wait for discovery until 1972. The [3, 2-b]-mode of fusion …

The photophysics of a structurally unique aza‐analogue of polycyclic aromatic hydrocarbons
characterized by 12 conjugated rings and a curved architecture was studied in detail. The …

By using strong electron donors (D) and acceptors (A), intramolecular charge transfer (ICT)
bands of dyes could bring new visions for structure-property relationship in …

Advances in Heterocyclic Chemistry, Volume 128, is the definitive series in the field—one of
great importance to organic chemists, polymer chemists and many biological scientists …

dihydro-1, 2, 4, 5-tetraarylpyrrolo [3, 2-b] pyrroles are a versatile class of materials with
simple synthesis and promising application in organic electronic devices. In this work we …
