Excited-state absorption and sign tuning of nonlinear refraction in porphyrin derivatives

Article Abstract:

The nonlinear absorptions and nonlinear refractions of free-base porphyrin and Zn-porphyrin are analyzed by using the Z-scan method. The results have shown that the sign of self-lensing is tuning by the coordination of Zn in the porphyrin derivatives and thermal effect has increased to dominate the nonlinear refraction sign.

Self-assembly and characterization of a novel hydrogen bonded nanostructure

Article Abstract:

A novel hydrogen-bonded supramolecular system of a [60]fullerene derivative with perylene bisimide is synthesized and characterized. The photocurrent response of the film is measured, and a steady and rapid anodic photocurrent response is obtained.
