The intramolecular charge transfer-driven emission properties of T and V-shaped donor-acceptor-donor molecules involving a new acceptor core of pyridoquinoxaline were demonstrated. The T-shaped molecule exhibits a large Stokes shift, red emission in the solid state and remarkable viscosity and temperature-dependent tunable fluorescence including a thermally-induced single-component near white-light emission.

In this report, we present solvent assisted excited-state proton transfer coupled to the deactivation of a photo-excited 2,2’-pyridylbenzimidazole bound water molecule. Experimentally, the mass-selected 1:1 complex was probed using two-colour...

The dispersion-controlled docking of inert Ar atoms on the face of polycyclic 2-(2′-Pyridyl)-benzimidazole (PBI) was studied experimentally aided by computational findings. The PBI-Arn (n=1-3) complexes were produced in a supersonically...

This article demonstrated experimental proof of excited state ‘solvent-to-chromophore’ proton transfer (ESPT) in the isolated gas phase PBI (2,2'-pyridylbenzimidazole)-CH3OH complex, aided by computational calculation. The binary complexes of PBI with...
