Transition-Metal-Free Benzannulation of Tricarbonyl Derivatives with Arynes: Access to 1,3-Dinaphthol Precursors for the Synthesis of Rhodamine Dye Analogues

Herein, we report a transition-metal-free annulation reaction of benzynes and 1,3-oxopentanedioate for the synthesis of highly functionalized naphthalene derivatives for the first time. Additionally, the representative naphthalene derivatives have been successfully transformed into the new series of rhodamine dye analogues.

Comprehensive study on excited state intramolecular proton transfer in 2-(benzo[d]thiazol-2-yl)-3-methoxynaphthalen-1-ol and 2-(benzo[d]thiazol-2-yl)naphthalene-1,3-diol: Effect of solvent, aggregation, viscosity and TDDFT study

Three compounds DMT, MMT and DHT having dimehtoxy, mono-hydroxy and di-hydroxy groups respectively were prepared. Environmental interactions dependent photophysical properties especially excited state intramolecular proton transfer (ESIPT), solvatochromism, aggregation induced emission enhancement (AIEE) and viscosity dependent emission characteristics were studied. The effect of solvent polarity on ESIPT dynamics were studied using UV–vis and emission spectroscopy along with aggregation induced enhanced emission and viscosity effect. MMT and DHT showed unexpected and contrasting behavior in the solvents which are in good agreement with the density functional theory and time dependent density functional theory findings. Aggregation and viscosity study showed that cis-keto emission increased drastically in the aggregate state and highly viscous state due to restricted intramolecular rotation increasing the population of required cis enol rotamer (E). The study directs the potential applications of such molecules for advanced optoelectronics and viscosity based investigations.
