The retinal protein protonated Schiff base linkage plays a key role in the function of bacteriorhodopsin (bR) as a light-driven proton pump. In the unphotolyzed pigment, the Schiff base (SB) is titrated with a pK(a) of approximately 13, but following

A covalently tethered dyad containing the azulene (Az) and zinc tetraphenylporphyrin (ZnP) chromophores has been synthesized and its excited-state dynamics investigated, using the tether-substituted monochromophoric species as reference compounds. On

In this review, we summarize the work carried out at the University of Hawaii on the highly colored, non-alternant hydrocarbon azulene. Through systematic perturbation of the HOMO and LUMO molecular orbitals, we showed that the characteristic azure c

[structure: see text]The diastereotopic methyl signals detected at low temperatures or high concentrations of an azulenylazulenium salt containing prochiral centers are consistent only with a model involving monomers in rapid equilibration with dimer

Hyper-Rayleigh scattering (HRS) has been carried out for new azulenic donor–acceptor chromophores using near-infrared laser excitation at wavelengths of 1064 and 1907 nm. Hyperpolarizabilities obtained with the 1064 nm incident excitation are large
