We report on the synthesis and the optical properties of several novel semiconductors (R-NH3)(2)PbX4 (X = Br-, I- or Cl-). These semiconductors are two-dimensional organic-inorganic perovskite (2DOIP) materials and have multiple quantum-well energy level structures. We vary the organic components (R-NH3+), introducing fluorine atoms into the organic part, on the phenyl ring of the amine. We discuss its influence on the self-organization ability and long-term photostability of the 2DOIPs. The trends of introducing fluorine atoms on the self-organization and long-term photostability of 2DOIPs are obtained by analysing the optical experimental results, and show that the influence of the fluorine position on the benzene ring is quite important. The most promising compounds seem to be the ones with the fluorine atom sitting on the para position of the phenyl group.
