Iridium(III) fac-tris(2-phenylpyridine) fac-[Ir(ppy)3] complexes equipped with longalkylchains were prepared to examine their capability to form organized arrays on the surface of highly oriented pyrolytic graphite (HOPG). The molecules form lamellar arrays at the 1-phenyloctane/HOPG interface. From the analysis of the STM images, it was concluded that the molecules align with alkylchains being
interface was transferred horizontally onto a hydrophobic glass plate as a Langmuir–Blodgett (LB) film. The emission from a single layered LBfilm was monitored under the atmosphere of various kinds of gases. As a result, molecules with functional groups such as –OH, CO and –CN were found to quench efficiently excited fac-[Ir(ppy)nL3−n] in a film. The effects of isotope and molecular chirality on energy
