“…BODIPYs have been extensively studied as fluorescent probes for bioimaging applications [138][139][140][141] but only scarcely for the design of photoinitiators [142][143][144]. The first carbazole-based BODIPY used as photoinitiator was reported in 2019 (Cbz_35) in the context of a polymerization carried out in the near infrared region (See Fig.…”

Photoinitiators of polymerization that can be activated under visible light and low intensity are actively researched as these compounds constitute the next generation of photoinitiators that will replace the controverted UV-photoinitiators. Over the years, a family of compounds has been identified as being highly promising in light of its remarkable photoinitiating ability, photochemical stability, low cost and easiness to functionalize, namely carbazoles. In this review, an overview of the different carbazole-based photoinitiators reported to date is presented. Interestingly, carbazoles have mostly been used as electron donors in push-pull structures, as photosensitizers for iodonium salts, as ligands for ferrocenium salts or as chromophores for phenacyl onium salts. These different applications clearly demonstrate the versatility of this structure used as the elemental building block for the design of UV, near-UV or visible light photoinitiators.

“…No evidence for the formation of the desired product was observed by NMR of the crude material. Tetraphenylethene derivative 7i was prepared in the hope that it would display aggregation-induced emission (AIE) [34][35][36], however, disappointingly, it did not. The yields of the reactions ranged from good to excellent.…”

Ready Access to Molecular Rotors Based on Boron Dipyrromethene Dyes-Coumarin Dyads Featuring Broadband Absorption

Herein we report on a straightforward access method for boron dipyrromethene dyes (BODIPYs)-coumarin hybrids linked through their respective 8- and 6- positions, with wide functionalization of the coumarin fragment, using salicylaldehyde as a versatile building block. The computationally-assisted photophysical study unveils broadband absorption upon proper functionalization of the coumarin, as well as the key role of the conformational freedom of the coumarin appended at the meso position of the BODIPY. Such free motion almost suppresses the fluorescence signal, but enables us to apply these dyads as molecular rotors to monitor the surrounding microviscosity.

“…Among them, RIM has been widely acknowledged as one of the origins of AIE. 19,20,[23][24][25][26] From single molecular states to aggregated states, the restricted moieties of different molecular systems are not identical ( Fig. 1A-C).…”
