“…They not only play momentus role in optoelectronics, displays and silver free imaging systems but also in bioactive naturals and non‐natural compounds. Keeping this in mind, spirotruxene derivatives 54 a‐f along with their photophysical properties have been reported by Kotha and his coworkers using cyclotrimerization, ring‐closing metathesis and Suzuki‐Miyaura cross‐coupling reactions as key transformations (scheme ) …”

Truxene and its congeners due to its structural, thermal, and optoelectronic properties, has recently became important not only in biological systems but also in the field of material and environmental sciences. The remarkable scope and its applicability ranging from sensory materials to photocatalysts and fluorescent probes, forces the scientific community to think about the design and construction of architecturally simple yet much powerful novel functional materials possessing the truxene scaffold(s) in their structures. Herein, we have focused to assemble a series of ground‐breaking achievements in recent years of truxene‐based functional materials with special emphasis on their applicability in material sciences and technology. We hope that the present review will boost the current scenario of truxene and its various domains.

“…Finally, sequential transformations consisting of oxidation, DA reaction, CR and RCM generated the ABCD fragment 17 of the fredericamycin A, involving seven steps (Scheme 3). 27 Carbon-rich polycyclic aromatic hydrocarbons (PAHs) have been attracting a great deal of interest due to their unique photophysical properties. We envisioned a new approach to truxene 18 and spirotruxene such as 21, as important building blocks for the preparation of aromatic dendrimers.…”

Cyclopentanoids and their derivatives are interesting targets in synthetic organic chemistry due to their extensive applications in various branches of chemical sciences like pharmaceuticals, natural and non-natural products. In view of these applications, several synthetic strategies have been developed in the past three to four decades. In this article, we describe our work towards the synthesis of cyclopentanoids and their heteroanalogs involving diverse synthetic strategies during the past two decades. Among these, photo-thermal olefin metathesis, ring-closing metathesis, ring-rearrangement metathesis, cyclopentane annulation, [2+2+2] cycloaddition, and Diels-Alder reactions have been used to assemble cyclopentane rings of diverse architecture.

“…It is really amazing that how time has passed and a plethora of novel synthetic breakthroughs, coupled with a range of revolutionary applications has drastically transformed this realm of modern science and technology. Not surprisingly, till date limitless functionalized truxenes and their isomeric isotruxene derivatives have been reported in the literature [23][24][25][26][27]. Since, the chemistry of truxenes is undoubtedly of great interest, therefore there is always a pressing need to develop simple yet powerful synthetic strategies and also novel truxene-based functional materials with unique properties.…”

Design, synthesis and properties of polycyclic aromatic hydrocarbons (PAHs) has historically attracted a considerable interdisciplinary interest from both fundamental as well as applied viewpoint on account of their wonderful optoelectronic properties. The scientific interest in two-dimensional star-shaped PAHs particularly in truxene architectures arises because of their high thermal stability, exceptional solubility and ease with which they can be constructed and modified. Therefore, bearing in mind a wide range of applications of truxene and its congeners, herein we reveal three novel distinctly different routes for the generation of C3-symmetric pyrrole-based truxene architectures by means of cyclotrimerization, ring-closing metathesis (RCM), Clauson–Kaas and Ullmann-type coupling reactions as key steps. Moreover, we have also assembled some other interesting heterocyclic systems possessing oxazole, imidazole, benzimidazole, and benzoxazole in the framework of truxene. Additionally, the preliminary photophysical properties (absorption and emission) for these versatile systems has been revealed.
