“…Researchers are emphasizing non‐fullerene OSCs, such as star‐shaped OSCs since they can directly absorb large quantities of sunlight [1]. Conjugated starburst molecules have received particular attention due to their well‐defined structures, high photoluminescence quantum yields, outstanding thermal stability, and excellent optoelectronic properties [2]. Various conjugated starburst materials with various cores, including truxene, pyrene, and triazatruxene have been designed and synthesized to demonstrate effective electroluminescence [3].…”

The role of dendrimers is getting updated and grabbing immense attention in many fields. Dendrimers are used in a broad spectrum, in specific, it is widely utilized in drug delivery, for targeted carrier and specific action. Also, in drug catalysis, it improves the solubility of poorly soluble drugs and increases the stability of active ingredients within the cores. Many researchers are interested in developing new dendrimers by using various compounds. ‐conjugated dendrimers via truxenes and thienylethynylene units, are considered a promising material in the field of medicinal chemistry, bio‐organic, and environmental sciences. In QSAR/QSPR, the structural analysis of chemical compounds is examined by topological descriptors. In this article, the various distance‐based topological indices such as Wiener, Szeged, and Mostar of gradient star‐persistent ‐conjugated dendrimers are determined. Since gradient star‐persistent ‐conjugated dendrimers have odd cycles, the usual cut method is not applicable, therefore we use a new concept, the quotient of quotient graph to determine the numerical expression of various indices. An analysis of linear regression reveals that degree‐based topological descriptors predict better physicochemical properties.

“…The introduction of flexible fluidic alkyl chains at C-2, C-7, and C-12 positions can enhance the solubility of planar C3 symmetric truxene derivatives. 19 In this regard, the trialkoxybenzene unit is attached to the central truxene core to augment the columnar stacking and solubility, forming star-shaped DLCs. Molecular design in the present work uses an alkynyl linker between truxene core and trialkoxybenzene moiety for two reasons.…”

Two new C3 symmetrical star-shaped truxene-based discotic liquid crystals have been designed to study their optoelectronic properties. Both the truxene derivatives exhibited columnar hexagonal self-assembly, confirmed by a thorough analysis using POM, DSC, and XRD. A multilayered OLED device was structured using these mesogens as blue emitters for electroluminescent studies. The best-performing configuration was perceived for devices based on emitter 1b at a dopant concentration of 1 wt% in a well-aligned CBP host, giving a maximum EQE of 2.9%.

Porous organic polymers (POPs), and especially covalent triazine frameworks (CTFs), are being developed as the next generation of metal‐free heterogeneous photocatalysts. However, many of the current synthetic routes to obtain these photoactive POPs require expensive monomers and rely on precious metal catalysts, thus hindering their widespread implementation. In this work, a range of POPs was synthesized from simple unfunctionalized aromatic building blocks, through Lewis acid‐catalyzed polymerization. The obtained materials were applied, for the first time, as heterogeneous photocatalysts for the aromatization of N‐heterocycles. With the use of the most active material, denoted as CTF‐Pyr, which consists of photoactive pyrene and triazine moieties, a wide range of pyridines, dihydroquinoline‐5‐ones, tetrahydroacridine‐1,8‐diones and pyrazoles were obtained in excellent yields (70–99 %). Moreover, these reactions were carried out under very mild conditions using air and at room temperature, highlighting the potential of these materials as catalysts for green transformations.
