Deposition of thermally unstable molecules with the spray-jet technique on Au(111) surface
Article Abstract:
A porphyrin derivative (5,15-bis(4-ethynylphenyl)-10,20-bis(3,5-di-tert-butylphenyl)porphyrin, trans -BETBPP) possessing chemically reactive substituents was successfully deposited on an Au(111) surface with a new molecular beam deposition system with use of a spray-jet technique without denaturing the molecules. The deposited molecular overlayers were observed at 77 K under ultrahigh vacuum condition by scanning tunneling microscopy.

Nonlinear absorption dynamics in tetrapyridyl metalloporphyrins
Article Abstract:
Z-scan technique at 532 nm is used to investigate nonlinear absorption dynamics of Zn(super 2plus), Cu(super 2plus), Ni(super 2plus) tetrapyridyl porphyrins in chloroform/methanol solution. A marked difference is observed in the nonlinear absorption and excited-state dynamics of closed (ZnTPyP)- and open-shell metalloporphyrins((CuTPyP)and (NiTPyP)).
