This article reports the design, and synthesis of D−π1–A−π2–D unsymmetrical, and D−π1–A−π2–A−π1–D symmetrical type of ferrocenyl-substituted benzothiadiazoles by the Pd-catalyzed Sonogashira, and Stille coupling reactions. The photophysical and electrochemical behavior of the ferrocenyl-substituted benzothiadiazoles show strong donor–acceptor interaction. The increase in the number of acceptor benzothiadiazole

A series of donor–acceptor ferrocenyl substituted bisthiazoles 3–8 were designed and synthesized by the Pd-catalyzed Suzuki, Heck, and Sonogashira cross-coupling reactions. Their photophysical, electrochemical and computational studies reveal strong donor–acceptor interactions. The photonic and electrochemicalstudies show that the ferrocenyl bisthiazoles with vinyl linkage ferrocenyl-bisthiazole 4

meso-Alkynylated ferrocenyl BODIPYs (3â6) with varying conjugation length have been designed, and synthesized using the palladium catalyzed Sonogashira cross-coupling reaction of meso-chloro BODIPY with the corresponding ferrocenylethynes. These BODIPYs have been designed to improve the electronic communication between the donor ferrocene, and the acceptor BODIPY. The photonic and electrochemical properties indicate charge transfer (CT) from the ferrocene to the BODIPY. Single crystal X-ray structures of 2â², 3, and 6 show interesting supramolecular interactions. Computational studies were used to study the electronic structure of the BODIPYs.

A series of C3 symmetric ferrocenyl-substituted 1,3,5-triazines has been designed and synthesized by the Sonogashira cross-coupling reaction. The photophysical and electrochemical properties of these triazines show substantial donor–acceptor interaction. The single crystal X-ray structure of triazine 3 is reported, which shows a planar structure. The supramolecular structure of 3 exhibits intermolecular π–π interaction, which leads to the formation of 2D layered structures.

β-Substituted ferrocenyl porphyrins were designed and synthesized by the Pd-catalyzed Sonogashira cross-coupling reaction. The UV-vis absorption, emission, and cyclic voltammetric results indicate strong electronic communication between ferrocene and porphyrin. The porphyrin 4a is non-emissive in nature, while 4b and 4c show reduced fluorescence quantum yield. The single crystal X-ray structure of 4b is reported
