Two photochromic diarylethenes blocked by alkyl bridges in an ideal conformation for photocyclization are studied stationary and femtosecond transient spectroscopy order to depict the processes: bistable 1,2-dicyano[2.n]metacyclophan-1-ene with n = 2, abbreviated as [2.2], its non-bistable analogue 4, [2.4]. The data interpreted light of AM1-CIS calculations state correlation diagrams based on conclusive TD-DFT calculations. For a solvent-sensitive excitation wavelength threshold governing...
The photoswitching and competitive processes of the referent photochromic diarylethene derivative 1,2-bis(2,4-dimethyl-5-phenyl-3-thienyl)perfluorocyclopentene (DTE) a novel bridged analog DTE-m5 have been investigated by state-of-the-art TD-DFT calculations ultrafast spectroscopy supported advanced chemometric data treatments. Focusing on DTE, overall deactivation pathway both antiparallel (AP) parallel (P) conformers open form (OF) (1 : 1 in solution) has resolved rationalized starting...
This work deals with the photophysics of a pyridinium betaine, 2-pyridin-1-yl-1H-benzimidazole (SBPa), based on combination steady-state, femtosecond photoionization (gas phase) and transient absorption (solution) spectroscopic measurements, supported by (LR)-PCM-(TD)DFT calculations. Preliminary new electrochemical results have revealed strongly negative solvatochromic charge transfer (CT) due to S0 → S2 vertical transition weakly-solvatochromic emission S1 transition. Advanced TDDFT...
The photophysical properties of an azacrown–iridium( iii ) complex, designed to trap and photo-release Ca 2+ , are investigated with ultrafast spectroscopy TDDFT calculations.
